The root (top-level) site for your organization can't be deleted. If you're a global or SharePoint admin in Microsoft 365, you can replace the root site with a different site.

After replacing the classic root site with a communication site , you can set it as a hub site later.

If your environment was set up before April 2019, you can modernize your root site in three ways:

  • i do not think your statement on The root (top-level) site for your organization can't be deleted is 100% correct ,, as we can remove the root

You can do a site swap. Short answer is that you can configure a new communication site, get it configured the way you want, then in the SP admin center, swap it with the root site to make it become the new root site.

Optionally, you can replace the home page with a full width modern page.

Instructions for this are available here.

  • if i do the swap what will be the url for the swapped site? the actual root url such as contoso.sharepoint.com? also can i set the swapped site as Hub ?
