Guys, we would like to replace Classic Team site (root site) to Communication site as root site. in SharePoint Online
And for the current root site there are several subsites associated to the root site.

So if we replace with comm site what happens to the "Subsites" and the permissions ?

I was referring the below MS Doc and it said "subsites, will be archived". What does it mean ? do users have access or no access to the subsites ?

https://learn.microsoft.com/en-us/sharepoint/modern-root-site#swap-your-root-site
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.

Please advise ?

    Hi @SR VSP ,

    It means if the classic site collection had subsites, they aren't changed. For Reference: Enable the communication site experience on classic team sites

    And here is a article about how to convert Classic Team Site to Communication Site.

    I would recommend to test it first: create test SPO tenant with classic site in the root with few sub sites, try to replace it with modern site and see what will happen on practice.
