Connecting Existing SharePoint team sites to existing Office 365 groups
As of now, we have option to connect existing SharePoint team sites to new Office 365 groups. But if there is an option to connect existing SharePoint sites to existing Office 365 groups, it will be good.
We are seeing a need for this as well. Two use cases off the top of my head:
During the early days of experimenting with Teams, people created teams and started using them. Once they realized the value, they wanted to then associate the existing Team with a previously-existing SharePoint site which already contained all of their documents and historical data.
For organizations which have not yet completed their migration from SharePoint on-prem to SharePoint Online, it would be useful to be able to associate a Team (or any O365 Group) with a pre-existing SharePoint site once it gets migrated to SPO.
