Move Conversion Blocks to a new theme

Blocks live in one theme. A copy of your theme keeps them, but a new theme needs them added again.

Updated November 4, 2026

Blocks live in one theme, so a new theme starts without them. Add them again in the new theme. A copy of your current theme keeps its blocks.

Add blocks to a new theme

  1. In Shopify admin, open Apps → Section Store → Conversion Blocks.
  2. On a block's card, click Edit In Theme.
  3. Pick the new theme.
  4. Set the block up and click Save.
  5. Repeat for each block.

Set up before you publish

You can set blocks up on an unpublished theme. Shoppers see them when you publish it. Live block status covers your published theme only, so it won't show them as live yet.

Your old settings

Your old theme keeps its blocks and settings. Keep it open in a second tab and copy the text across.
