Symptoms
When running a pre-check or a migration in ShareGate Migrate, some files display the following error message:
The mapped Sensitivity label would remove encryption, which is not supported.
Error codes
AN-141-548
Details
When migrating within the same tenant, ShareGate Migrate cannot remove encryption from a file to apply a new Sensitivity label without encryption.
Removing encryption would leave the file unprotected, which is not a supported operation during migration.
Solutions
Solution 1: Map to an encrypted Sensitivity label
Map your Sensitivity label to a label with encryption at the destination.
Retry the migration for the affected files.
Solution 2: Migrate and relabel manually
Migrate the files as-is with their current encrypted label.
After migration, manually apply the desired unencrypted label at the destination.
Note: You must have the necessary permissions on the file to remove or modify encryption after the migration.
