Modernizing Root Sharepoint Site Withour Losing Subsites

Question

I have a hybrid of classic teamsites (under /, e.g. /. /HR,/ IT) along with O365 group and other modern sites (all under sites/). I tried to replace my root (classic Teamsite) site with a modern site. It worked, however the root site has a bunch of subsites and all of them were archived. I restored the whole collection with Invoke-SPOSiteSwap but I still would like to replace just the root site with a modern experience. How can I do this without losing all those subsites? Thanks!

Answer 1

If it is only support for modern pages you are after (not sure how long we should keep calling them that!) you only have to activate the Site Pages feature.

1. Under Site Settings and Manage Site Features activate the feature Site Pages
2. Go to Site Contents, find the newly created Site Pages library
3. In this library, create a new page of type Site Page
4. Set this as your home page
