After you successfully migrate data from Dropbox to Workspace, you can move any newly added and updated files or folders to your Workspace account before you exit the migration. To transfer the new content, run a delta migration in Workspace.
What is a delta migration?
A delta migration identifies changes to previously migrated files or folders, such as changes to permissions, and updates the files or folders in Workspace.
A delta migration skips items that have already successfully migrated but haven't been updated in your Dropbox account. These items are marked as skipped.
| Delta migration task | Changes in Google Drive |
|---|---|
Update changes or additions to Dropbox files and folders since the last migration, including:
|
Updates migrated to files in Drive |
| Update permissions or user deletions from sharing lists | Updates migrated to files in Drive |
| Update deleted Dropbox files and folders | Previously migrated files and folders aren't deleted in Drive |
What if I edit the list of files I'm migrating?
If you change the comma-separated values (CSV) file that lists your migrated personal and team folders before you run a delta migration in Workspace, the new data migration service makes the following updates:
- Add a user or team folder path to the CSV file—The folder migrates to 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 Drive remain unchanged.
What happens if I update my identity map?
If you update your identity map before you run a delta migration in Workspace, the results depend on whether the identity map includes the user that you updated.
| Change | Identity map includes user | Identity map doesn't include user |
|---|---|---|
| Adding user | The account's personal folder and user permissions migrate to Workspace. | The account's personal folder and user permissions don't migrate. |
| Deleting user | The migration completes with an error indicating that the identity mapping is missing. | Any previously migrated user permissions are deleted. Files and folders that already migrated don't change. |
| Updating user | Previously migrated files don't change, but new files and folders are created in Workspace to match the new mapping. | NA |
