Change Root site

Copper Contributor

Hi ,


I have  a root site which isn't using the modern UI, I've created a new communications site. which I would like to set as my root site.


I'm am worried about making this change as I have a number of subsites which currently hang off the current root site. 

Can I change the root site without impacting on the existing subsites?

Hello @WilfiR 


see more informations here:


This item is listed under limitations :

  • Replacing the root site with another site replaces the entire site collection with the new site collection. If your current root site has subsites, they'll be archived.

Thanks - if the subsites are archived, can I edit their URL to hang off the new root site?

Hi @Wildlifer780 


you need to move it, best with third party tools like sharegate.


Best, Dave

Thanks - could I simply edit the url to reflect the root site change?
How does a root site change impact on sites linked to Teams Channels / Groups?

Hi @Wildlifer780 


it will automatically create redirects. Also in the article:

- If you disabled site redirects, you'll need to update sharing links and any apps or files (like the OneDrive sync app and OneNote files) to refer to the new URL.
