View [Changelog](/minimog-theme/changelog).

</Hint>

Section groups give merchants the flexibility to add, remove, and reorder sections in the theme layout without making changes to the theme code. To learn more about this feature, see [this article](page://2acab7f5-d8a7-4bec-8dea-3396c7df518f).&#x20;

If your current Minimog version is 3.3.0 or older, follow the quick steps below to migrate data of the Section groups feature after [updating the theme](page://9ca22aa7-9f47-4200-b33b-e18fd9aca704) to the latest version.

There are four sections that need to be migrated, namely:&#x20;

* Announcement bar;
* Header;
* Footer;
* and Mobile sticky bar.

If you don't use the Announcement bar in your current theme, there is no need for you to migrate the data of this section.

<Hint type="success">

Steps:

1. In your Shopify admin, locate your updated version, and go to **Actions** > **Edit code**.
2. Access the file **settings\_data.json.**
3. In the old version, locate and copy the code of each section, then move it to the relevant files of section groups of the updated version
   1. **header-group.json** (for the announcement bar and header section); or
   2. **footer-group.json** (for the footer and mobile sticky bar section).
4. Click **Save**.

</Hint>

**For example**: Copy the entire code of the Header (below the code line `"type": "header",`).

Then, go to **header-group.json,** replace the current content of that section (below the line`"type": "header",` - around line 17) with the copied content.

Do the same with other sections.

* Announcement bar: find `"type": "annoucement",`
* Footer: find `"type": "footer",`
* and Mobile sticky bar: find `"type": "mobile-sticky-bar",`
