Shopify theme upgrade (customizations kept)

Your theme is out of date, but it holds custom work you paid for. I move that work onto the new version in a preview theme, and nothing goes live until you have checked it.

What's included

  • A list of the custom code, sections and app blocks in your current theme
  • The new version installed as a preview, with your live store untouched
  • Every customization moved across and retested
  • All templates checked on desktop and mobile, plus Shopify's theme checker
  • A copy of the old theme kept, so you can switch back

Sounds familiar?

  • Your theme is several versions behind, and new features never reach your store.
  • A developer changed the code, and you are afraid an update will wipe that work.
  • Shopify says your code edits could not be included in the update.

If one of these is yours, send me a link and a few lines. Describe your task

    A link and a few lines is enough.

    On a preview theme. Nothing goes live without your OK.

  4. Step 4: Pay on delivery

    Exactly the estimate. Nothing added later.

    Projects up to 20 hours usually need no prepayment. Bigger ones are agreed individually.

Questions

Can't I just press Update in Shopify?

Theme editor settings are copied over, but Shopify warns that code edits may not be. If your theme has custom code, someone has to move it by hand and test it.

Will customers see anything while you work?

No. The work happens on an unpublished theme. You review it through a preview link and decide when it goes live.

Have you done this on a live store?

Yes. For Kidoriman, a clothing brand on Shopify Plus, I started from the clean new theme and re-applied every customization. It is now the live theme, with no new theme-check errors.
