Are you wondering what you should do before you change WordPress themes?

When switching your WordPress theme, there are few very important steps that you must take to ensure the process is smooth, and you don’t lose any important data. 

In this WordPress checklist, we’ll share the top things you must do before you change WordPress themes.

12+ things you must do before changing WordPress themes

Editor’s Note: If you’re looking for step-by-step instructions on how to switch themes, then please see our beginner’s guide on how to properly change your WordPress theme.

Switching a theme is an important decision that every website owner makes at least once every few years.

Of course you have to decide your reasoning of why you’re switching, and pick a theme that suits all your needs.

We have a list of best WordPress multi-purpose themes and best WordPress blog themes that you can check out if you’re looking for recommendations.

Once you have chosen the theme that you want to switch to, it’s important that you follow the checklist below to ensure that you don’t lose any content or data during the process.

1. Make Note of Any WordPress Theme Customizations

Some WordPress website owners will customize their WordPress themes by adding code snippets directly to their theme files. Code snippets can be a great way to add new features to your website that aren’t part of the stock theme.

But, if you’re adding those snippets directly to your theme files, it can be easy to lose track of them.

If you or a web developer made these changes, then make sure you go through your current theme files and note all of the additional code that’s been added. 

For adding code snippets in the future, we always recommend to use a code snippets plugin such as WPCode. This way, you can keep those snippets even if you change themes later. For more details, see our beginner’s guide on pasting snippets from the web into WordPress.

2. Get Current WordPress Theme Performance Metrics 

Before changing your theme, you should check your current website’s loading speed and performance. This lets you compare any differences in the page load time after you switch themes.

Since WordPress speed and performance plays an important role in user experience and WordPress SEO, you need to ensure the new theme is faster than what you’re using now. 

You can easily check your current website speed metrics using a WordPress speed testing tool such as IsItWP’s free website speed testing tool.

For more details, see our guide on how to run a website speed test.

3. Make Note of Current Theme Sidebars and Widget Areas

Sidebars are used for adding different widgets to your website, like email newsletter subscription forms, social media buttons, popular posts, and more.

Since every theme has different widget areas, your widgets may unexpectedly move or disappear from your site if you switch themes.

That’s why it’s important to make a note of what widgets you’re using in your WordPress sidebars and any other widget areas of your website before you change themes. Then you can easily replicate them after switching.

If you’ve added any custom code or shortcodes, then make sure to copy this code and save it somewhere safe so that you can use it with your new theme. 

4. Copy Existing WordPress Tracking Codes

Many users will add analytics tracking code directly to their theme files. Some WordPress themes also allow you to add tracking codes directly into your theme options panel.

It’s a common mistake to overlook these important tracking codes. 

You need to make sure you copy all of your website tracking codes you’re using for analytics, advertising, and more, so you can add them to your new website. 

If you want to make it easy on yourself, then we recommend using a plugin like MonsterInsights to install Google Analytics in WordPress.

By using MonsterInsights, you can rest assured there will be no interruptions to your analytics or lost data. You’ll also unlock bonus tracking like link clicks and button click tracking, WordPress category and tag analytics, author tracking, and much more.

MonsterInsights

For all other tracking codes, you can use the free WPCode plugin. For more details, see our guide on how to add header and footer code in WordPress.

5. Back Up Your Current WordPress Website

It’s always a good idea to back up your website on a regular basis. Before changing your theme, you should completely back up your posts, pages, plugins, media, and databases.

The easiest way to do this is by using a WordPress backup plugin to create a backup of your entire site.

We recommend using the Duplicator plugin. It allows you to easily create automated, scheduled backups and save them on cloud storage services like Dropbox, Google Drive, and more.

Duplicator

There’s also a free version of Duplicator to get you started. For more details, see this guide on how to backup a WordPress site.

This will help ensure you can easily recover your website if anything goes wrong when switching themes. 

6. Put Your WordPress Site Into Maintenance Mode

When making changes to your site, it’s always a good practice to put your website into maintenance mode. Maintenance mode lets you display a user friendly notice to your visitors.

Maintenance mode page example

This helps prevent your visitors from seeing your website when it’s half-finished or under construction.

To do this, we recommend using the SeedProd plugin. It’s the best drag and drop WordPress page builder used by over 1 million websites.

It lets you easily create custom maintenance mode pages, landing pages, coming soon pages, 404 pages, and more. 

SeedProd

For more details, see our guide on how to put your WordPress site in maintenance mode.

7. Test All Functionality and Installed WordPress Plugins

Once you have a new WordPress theme activated, you need to ensure you have the same functionality as before and that all of your old plugins work with your new theme.

You can start by adding back the code snippets that you copied from your old WordPress theme files. For more details, see our beginner’s guide to pasting code snippets into WordPress.

Then, spend some time using the features of your site that are powered by WordPress plugins. If you’re experiencing any errors at this time, see our beginner’s guide to troubleshooting WordPress errors.

8. Test New WordPress Theme Across Browsers and Devices

Cross-browser testing will help you make sure your new website looks good on different browsers, screen sizes, operating systems, and mobile devices.

Most of your visitors will probably use Google Chrome to visit your WordPress blog. However, other web browsers like Firefox, Microsoft Edge, Safari, and more are still used by hundreds of millions of users worldwide.

If your new website doesn’t work right on one of those browsers, then you’re missing out on visitors and traffic. 

Luckily, you can use all kinds of cross-browser testing tools to see how your website looks across different browsers and devices.

For more details, see our guide on how to test a WordPress site in different browsers.

9. Delete WordPress Plugins You No Longer Need

Some WordPress themes will pre-install plugins when you install the theme. Some of these may be useful, but other times you won’t need them.

Simply go to Plugins » Installed Plugins to see if your theme has added any new plugins.

List of installed plugins

Now is also a good time to go through your entire plugin list to see if any plugins are worth deleting. 

If you’re looking for high quality plugins to use with your new theme, then see our picks of the must have WordPress plugins. 

10. Let Your Users Know Your New Website is Live

Once you’re ready to make your new WordPress theme live, you can turn off maintenance mode.

You should also get in touch with your readers to tell them about your new website. This will prepare your audience so that they’re not confused by any big design changes, and it will also help to keep your subscribers engaged and returning to your site to see the new design.

Here’s an example post we shared on Facebook about our new website redesign.

Redesign announcement example

We recommend notifying your audience via your email newsletter, social media, and push notifications.

If you’re looking for more ways to promote your site, then see our guide on how to share your blog posts with readers.

11. Test Loading Speeds for Your New WordPress Theme

Once your new theme is live and you’ve gone through the steps above, it’s time to do another speed test. Ideally, your new website will be faster and get better scores in your speed test.

To do this, simply use the same website speed tool you used earlier and compare the results. 

If the new theme is slower than your old theme, then make sure you run multiple tests, test from different areas, and check to see if you have any caching or firewall settings that could be causing the dip. 

12. Monitor Your WordPress Website Bounce Rate

Bounce rate is the percentage of visitors who land on your website and leave without continuing to a second page. A high bounce rate means that you didn’t convince your visitor to stay on your site long enough to take action.

After you switch themes, it’s important to monitor your bounce rate. Some themes are simply friendlier at helping visitors navigate around your site.

If your bounce rate has gone up since switching theme, then you’ll want to work to lower it. You can do this by improving your navigation menus, adding a popular posts widget, adding more internal links, and more.

For more details, see our guide on how to increase pageviews and reduce bounce rate in WordPress. 

13. Listen to Reader Feedback to Improve Your WordPress Website

Finally, it’s important you listen to reader feedback after you switch to a new theme. Some readers may love or hate certain parts of your design. 

You don’t have to listen to every reader and make the changes they suggest. But, if there’s a group of readers who are experiencing the same issue, then it’s probably worth looking into.

You can collect visitor feedback by adding a contact form to your website, or running a survey asking for reader feedback on your new design.

The easiest way to do this is by using WPForms. It’s the best WordPress survey plugin in the market used by over 5 million websites. 

WPForms

It lets you easily create engaging survey forms with the drag and drop builder.

Plus, the reporting section automatically creates beautiful reports to help analyze your results. 

WPForms Survey Results

For more details, see our guide on how to create a survey in WordPress.

  10. Thank you for sharing those valuable tips with us. Migration from a wordpress theme to another is not as easy as one might think espcially when it comes to complicated themes that require certain skills.

    It took me one week to migrate to my current theme and those are the steps i followed:
    1- backing up database and files (wp-content folder).
    2- importing the database and the files to a localhost to explore the new theme.
    3- restoring backup after making necessary changes to the server.

  12. Hi,

    I am considering temporarily changing theme as my theme (free theme Virtue) for whatever reason doesn’t give access to the header or footers and I need to add some code to have my site verified. I have tried everything – also uploading the file using filezilla and that was also rejected! I would rather not change theme if I can avoid it as I like a lot about Virtue – but can you tell me what the effects of changing theme temporarily and then changing it back – (of course, I would back everything up) but would it cause an issue for the site to change, put in the code – get verified and then change back – or would I find a lot of things changed when I get back!?!?

    Thanks,

  15. Great article. Thanks for list.
    I’m a total beginner in coding and WordPress. My current WordPress site (non-responsive and Genesis Prose theme) was done by a developer (no longer use him). I find that Genesis is too hard for me. Now I want to change the theme something that is easy for me to install and update without an experienced web developer, maybe like GeneratePress. If I change theme, will I lose all my Google search indexing that I’ve accumulated over the years?
    Thank you again.

  16. Hi Thanks for the article. I have a word press zerif-pro theme “shared on wix-theme. I have had alot of people tell me they can’t open my website on there iPhone and I am wondering if this is a server compatibility problem. I also have run into problems with not being able to carry out automated deliveries through my PayPal plugin on the site even though I have filled it all in correctly. I was told to take it out of the wix theme and buy it directly to possibly fix these issues. Have you heard anything like this before? Plus how would one take it out of wix theme and just pay for the premium site? I had some one from fiverr do it for me originally . Thanks for your time and your site!!

My site is fully approved by Google adsense… But now after deactivating maintenance mode, my adsense ads are not showing… I thought it may take some time so placed the ad on side bar…. But after 2 days, it still not showing any ads…. I am a newbie to blogging so please help me out…

    • Please refer to the troubleshooting section in Adsense support website. You may want to test if the Google Adsense bot can crawl your website. You may also want to check your site in webmaster tools to make sure that Google crawlers can crawl and index your website.

  24. Hi,
    My biggest concern is losing the Yoast SEO data after migrating to a new theme. Since the interface in the new theme is going to be so very different than my current theme, I think I’ll have to manually re-publish my pages in the new theme keeping in mind that the new pages retain their old “SEO Title” and “Meta Description”.
    Whats your take on it??

  27. Hello,
    We are currently using Classifier on our community based site and after a trial run are considering switching to FacePress…any idea how time intensive this switch could be? And would it require a shut down of the current site for longer than your suggested 20-30 minutes to implement the change?

    Reply

    • We would recommend creating an staging environment on your localserver first. Once you know what needs changing you can export those settings (Depends if the theme has theme settings export/import feature) or make a list of changes to implement. The actual time may vary. Each site is different and you may come across an issue that would require more time in fixing.

    • You probably have a caching plugin like “WP Super Cache” or “W3 Total Cache” installed on your website. If this is the case, then you will need to disable the caching plugin and then visit your website. You can reactivate the plugin later.

  33. Hi,
    I just found your article which came at a great time because I’m thinking about switching from WP Twenty Twelve to a Genesis Theme. But I’d like to know whether my posts that I already have on my blog will be automatically updated when I make the switch. Or, do I have to manually update and publish each post when the new Genesis theme is installed?
    Thanks,

    • Switching a theme does not affect your posts in any way. When you will switch theme WordPress will automatically display your posts with the new theme. In case if you don’t like your new theme, you can always deactivate it and reactivate your old theme.

    • Sometimes premium themes display images and sliders in their demo which are actually not included in your theme. You have installed your theme correctly. Please contact the theme developer for support.

  35. Hello there,

    I am so glad that I found your blog. I am new to wordpress.org and I’ve never used their software before. Although I am a bit familiar with blogspot.com but since joining wordpress it’s a big transition.

    I have just hosted my sites with hostgator and I really like their customer support and the cPanel.

    Anyway, my main questions are the following:

    1) I am about to start building my blog on wordpress but because this will be a long term investment and I wasn’t sure whether to select one of the free wordpress themes that allows me to customize once installing them or buying a wordpress paid theme. However, if I decide to change my theme in future (e.g: if my site becomes successful and if I’ll be able to monetize) I might want to change to a paid theme. Is this going to be a hassle changing from a free wordpress theme to a paid theme? If this can be done in future, do I have to backup all the time? My hostgator package will back up my sites everyday. Is it necessary for me to back up still on BackupBudy before installing to a new wordpress paid theme? Obviously, I don’t want to lose any of my contents.

    2) I am also worried about using the wordpress free theme because I’ve read everywhere that whenever wordpress updates its software the current free theme that people are using may not be compatible with the new wordpress update. However, I went to wordpress.org/freethemes there are quite a few reliable free themes that provides support and developers are also up to date with their themes to keep up with the compatibility with wordpress and therefore wordpress users are satisfied too.

    To conclude, would you suggest that I would use wordpress free theme for now (as I am still a beginner and still trying to build my site on wordpress) and change to a paid theme later once it becomes successful? Hostgator backs up my contents all the time, do I still need to backup before changing to a new theme? That’s all for now, thank you very much for providing these information. It’s very useful for newbies. :) I hope you can reply to my questions above as soon as you can.

    I am your new reader from now on and will be bookmarking your site.

    • Bel, welcome to the WordPress community.

      1. Backup. Yes you should still backup your site. If you do not want to invest into BackupBuddy right now, then you can create a complete WordPress backup for free with BackWPup. However, BackupBuddy comes with premium support and we highly recommend it.

      2. Free themes can be very reliable too, themes in WordPress theme directory go through extensive testing before getting approved. Create a child theme to customize your WordPress theme so that when there is a new version for your theme available, you can update it without loosing your changes.

  36. Thank you for an excellent resource. I took the plunge and started building my site myself at the beginning of this month. You were an awesome help as I am not all that PC literate. I am now seriously considering changing my theme as my initial goal with the site has changed since getting a feel for word press. I suppose that ones goal should determine the choice of theme? Therefore asking for advice on cool themes may be a waste of my time? Should I rather concentrate on functionality than looks?

    Reply

    • Functionality always trumps looks in our eyes. Yes asking for cool theme suggestions is a waste because beauty is in the eyes of beholder. Also you are the only person who knows exactly what you want in terms of functionality.

  40. Currently going through a WordPress one-on-one bootcamp with a seasoned WP developer. I’ve hit three of his WP-Black-Holes and “Changing Themes is Easy” is the third one. Changing themes is easy if you have a simple theme with minimal customization BY THE DEVELOPER. If a theme has 8 custom admin areas for sliders, additional menus, special content areas within the post area or sidebar, etc, and you switch themes to something you think “looks nice” you are in for a nightmare. DEFINITELY not “just a few clicks.” “Changing Themes is Easy” is a total myth. Just read this article and ask yourself, “Does it sound like just a few clicks?” Really?

    WordPress would be better if there were more honesty from the development community about the realities of using it as a CMS. Still a great checklist for what to watch for when changing themes.

    Reply

    • Any developer that tells you that changing themes is easy is probably NEW or do not understand the reality themselves. Blaming the entire community based on your experience with a few is not fair. We created this article for this vary reason.

  45. Really helpful suggestions! Some of them I really overlooked. I use Lubith in order to design and change my wordpress themes so most of the compatibility problems I haven’t yet encountered. It’s a very flexible and intuitive editor, you work directly in the browser which means you can test immediately the compatibility between the editor and your WP site or between your theme and your browser and you can quickly make the required modifications.

    Reply

  46. Thanks for the checklist…will prove helpful tomorrow when I change my theme. I am a bit concerned that old files from my older themes will linger when simply changing themes. Does anyone know if this happens or does switching themes wipe everything clean? I just want to make sure I’m starting with a clean plate.

    Also, you mentioned “WordPress SEO” by Yoast. Is that better in your opinion than “All in One” or “Platinum SEO”? Thanks for any response.

    Reply

  47. Just one word of advice on using some of the Maintenance plug-ins. Some of them (be sure to check out WordPress forum feedback) tend to bog down servers, resulting in unreachable WP Admin, and in the worst case scenario have your host shut down the account or charge you extra.
