To update your theme using Theme Updater, your theme must be supported and registered.
Update your theme

2. Locate your theme then click Update theme.
If you see a Register theme button instead, click this to register your theme before updating
3. Add a Theme name for the new, updated theme.
4. Make sure you have Preserve customizations enabled to transfer content, customizations, and theme setting configurations to the latest version.
5. Click Update to apply the update.
This adds a new theme draft to your Online Store.
The duration for each update varies depending on the level of customization and other factors.
Review the update
A modal window will appear once the update is complete.
This indicates the update was successful. Click Close to dismiss or open the theme editor by clicking Customize theme.
Some files still require a manual update
When modifications to the theme files are unable to transfer automatically, these instances are gathered and listed on the Conflicted Customizations page.
To view a list of adjusted theme file names, click Show Conflicted Files.
Click View Conflicted Customizations to see more details of the untransferred adjustments.
Compare file merge conflicts
File merge conflicts are side-by-side comparisons of the theme code in its default form (red) and the adjustments identified (green). Use these to determine if the code can be repurposed for the new theme version or if a Shopify Expert is needed.
Each theme file identified as Changed will feature a label and a Show code button.
Click Show code to reveal the code changes.
