How do I update the theme safely?

Update without losing changes: duplicate, compare, migrate settings, then publish.

Theme updates are easiest when you treat them like a controlled release.

Safe update workflow

  1. Duplicate your live theme (keep a rollback).
  2. Add the new theme version as an unpublished theme.
  3. Compare key templates:
    • header/footer
    • product
    • collection
    • cart
  4. Reapply settings and blocks carefully.
  5. Test end-to-end (mobile + desktop).
  6. Publish when validated.

Pro tip

Keep a lightweight "theme changes log" so you know what was custom vs default.
