I have a GROUP#0 site with GroupID and RelatedGroupID a valid Guid but that Guid points to a 365 group that was deleted long ago (not in the deleted groups)
Is there away to clear GroupID and RelatedGroupID so I can use "Connect to new Microsoft 365 Group" to assign a group to the site? Or a way to change site's template GROUP#0 to STS#3 and then use "Connect to new Microsoft 365 Group"
