OneDrive

Migrating to/from OneDrive using just UPN (user’s email)

You must create a mapping between the email domain used for the user’s UPN and the corresponding SharePoint Online tenant that is hosting the user’s OneDrive.

*Add the mappings in the list OneDrive Mapping .
If you are migrating between 2 different tenants you must make 2 mapping items.

Example	Teams/SharePoint
To copy to/from the OneDrive associated with the user sj@migratedms.com, where the SharePoint Online root site of the tenant hosting the OneDrive is https://MyTenant.sharepoint.com, you must map migratedms.com to MyTenant
The URL generated in the above example is: https://MyTenant-my.sharepoint.com/personal/sj_migratedms_com/documents
