After you successfully migrate data, you can still move any newly added and updated files or folders to your Workspace account before you exit the migration. Run a delta migration to transfer the new content.
What is a delta migration?
During a delta migration, any files or folders that were added or updated in your OneDrive account after your last migration are migrated to your Workspace account. The delta migration service also identifies changes to previously migrated files or folders, such as changes to permissions, and updates the files or folders in the Workspace account.
A delta migration skips over objects that have already successfully migrated and haven't been updated in your OneDrive account. These items are marked as skipped.
|
Delta migration task |
Changes on Google Drive |
|---|---|
|
Update changes or additions to OneDrive files and folders since the last migration, including:
|
Updates migrated to files in Google Drive |
| Update permissions or user deletions from sharing lists | Updates migrated to files in Google Drive |
| Update deleted Dropbox files and folders | Previously migrated files and folders aren’t deleted in Google Drive |
What if I edit the list of folders I'm migrating?
If you change the CSV file that lists your migrated personal and team folders before before you run a delta migration, the new data migration service makes the following updates:
- Add a user or team folder path to the CSV file—The folder migrates to Google Drive.
- Delete a user from the CSV file—The folder isn’t included in the migration, but any files or folders that already migrated to Google Drive remain unchanged.
What happens if I update my identity map?
|

|
Update a user |
Previously-migrated files don’t change, but new files and folders are created in Workspace to match the new mapping. |
