Can anyone offer guidance on how to update the theme safely without affecting my existing custom work and content?

Also, I’m thinking about switching to a new theme later on.

How can I do this while keeping all my content, like product listings and custom designs, safe?

Hello @RebeccaWil ,

Honestly, changing a theme is not a trivial thing at all. It can cause visual issues related to the placement of logo, fields, icons and any blocks, especially, if they are added as custom. It may also influence behaviour of apps which add custom logic to the front-end. If you don’t have technical knowledge, it is important to find a reliable Shopify development company that can help you with this process. They will be able to identify and solve any potential issues that may arise during the theme change to ensure a smooth transition.

Anyway, it is better to backup your current theme to secure yourself if anything goes wrong:

  1. Navigate to your Shopify Admin tab.
  2. Go to your online store and access the Themes tab.
  3. Click on Actions, followed by Duplicate.
  4. Download the theme to have it as a backup.

Before updating to a newer version, make sure that the theme is compatible with the current version. Make a note of all customizations you’ve made, including code changes, custom designs, and any additional features. Use Shopify’s built-in export features to save your product listings and other content. Apply customizations to the new theme gradually, testing each change to ensure everything looks and functions as expected.

Please, let me know if you need any assistance.

Best regards,
Anastasia

Hi Stacy,

I just purchased a new theme to my Shopify store and appreciate your feedback. I have also heard …but not sure..that I will loose my Google Analytics when updating to a new theme. Is that true?

Is there any support for specific themes? I purchased Empire and my 2-3 year old theme id not even available anymore. Is the previews reliable to how it will function and look and publishing the new theme?

Thank you,

Sus

Hi,

Shopify have added several features so updating a theme will not be a pain but unfortunately, any custom code you added to the theme will not transfer. You will need a developer to make sure that codes are compatible with updated theme.

Hi @IAM-test ,

Your Google analytics code will not transfer. You should be able to copy/paste the code to your new theme. If you still need help in updating your theme, we can do that for you for a competitive price. Just contact us through our website, see information below.

Will the websites carry on working with the upgrades?

It all seems to complicated to update by the looks of things…
