Hello, @theek This is how a theme is updated. You can update the theme from here.
Thanks!
Topic summary
A user is encountering an error when attempting to update their Dawn theme from version 12.0.0 to 15.2.0. The error message indicates that customizations cannot be copied to the new theme due to schema changes, such as modified block limits or section constraints.
Identified Cause:
- The large version gap (12.0.0 to 15.2.0) creates incompatibilities between old customizations and the new theme’s schema structure.
- Schema changes in newer versions may conflict with existing customizations.
Recommended Solutions:
- Backup the current theme by creating a duplicate before making changes
- Export and document all customizations (code changes, settings, sections)
- Test the update on a staging/duplicate theme first rather than the live site
- Compare schemas between versions to identify structural differences
- Manually reapply customizations to the new theme version
- Thoroughly test functionality and design after migration
One responder suggested downloading the new theme as a fresh installation rather than using the built-in update feature. The discussion remains open with no confirmed resolution yet.
