Microsoft 365 to Microsoft 365 (OneDrive/SharePoint) Considerations
When migrating files between Microsoft 365 tenants, Transend uses a combination of proprietary tooling and field-tested methodology to deliver maximum data fidelity. It is important to understand the various considerations when migrating data between OneDrive/SharePoint environments.
Ownership
Ownership of data in OneDrive is defined by the user who owns the drive. This is an inherited property that cannot be changed. Drives are migrated between pairs of source and target users, and this generally leads to the expected ownership structure after the migration.
Ownership of data in SharePoint is defined by the membership of the site’s Owners group. Ownership is defined during the provisioning process, when creating the target sites.
Permissions
Owners can grant access for other users via the Can edit and Can view roles on folders and files. These roles can either be set directly on a file or set on a parent folder and inherited at the file level.
- Direct permissions are permissions applied to a file.
- Inherited permissions are permissions applied to a folder and propagated to folders and files inside that folder.
Direct and Inherited permissions are maintained even if email addresses are changing during migration.
What isn’t migrated?
Member permissions are permissions applied to an entire shared drive. In SharePoint, this is via the various default SharePoint groups at the site level. These permissions are set during shared drive provisioning and do not migrate. They do not apply to user drives.
Folders have an additional Can’t download role that can be assigned. Microsoft does not support this role in its API, which means it is not supported for migration.
Link permissions are permissions applied via a sharing link and are not supported for migration.
