Microsoft announced Known Folder Move (KFM) for OneDrive

User content is automatically synced to OneDrive with no disruption to productivity. Behind the scenes, KFM moves content into OneDrive so it’s always synced to the cloud, protected, and accessible from all user’s devices. IT admin can deploy a group policy to users in your organization to encourage them to perform KFM. More details here.

Eligible end users can get to the KFM experience if they click on one of the KFM toast notifications or in OneDrive settings > AutoSave > Update folders.
