Understanding "Migrated with Issues" and "Partially Migrated" Statuses in OneDrive Migration Tasks (4378643)

After completing a OneDrive migration task, users may notice that some OneDrives are marked as Migrated with Issues or Partially Migrated. Understanding the difference between these statuses is crucial for determining whether further action is needed.

The two statuses have distinct meanings:

• Migrated with Issues:

  • Some content was migrated, but errors or warnings occurred during the process.
  • These errors may be related to file permissions, unsupported file types, throttling, or network disruptions.

• Partially Migrated:

  • The migration was completed successfully, but the source OneDrive item count is larger than the target item count after migration.
  • No errors occurred during the migration, but a discrepancy in the number of files exists.
  • This can happen if:
    • A user uploads new files to the source OneDrive while the migration is in progress. Since the migration only captures data at the time of execution, these newly added files won’t be included in the target count.
    • Some files were excluded due to migration filters.

For "Migrated with Issues":

1. Review the migration logs for details on any files that failed to transfer.
2. If needed, retry the migration for affected items.

For "Partially Migrated":

1. Check the task event details for insights into the item count mismatch.
2. Verify whether users were actively uploading files to OneDrive during migration.
3. Confirm if any filters were applied that could have excluded specific files.
4. If necessary, perform a resync or re-migrate the affected OneDrives to align the source and target item counts.

By understanding these statuses, administrators can determine whether the reported difference is expected due to real-time changes or if corrective actions are needed.
