After you successfully import data, you can still move any newly added and updated files or folders to your Workspace account before you exit the import. Run a delta import to transfer the new content.

What is a delta import?

During a delta import, any files or folders that were added or updated in your OneDrive account after your last import is copied to your Workspace account. The data import tool also identifies changes to previously imported files or folders, such as changes to permissions, and updates the files or folders in the Workspace account.

A delta import skips over objects that have already successfully imported and haven't been updated in your OneDrive account. These items are marked as skipped.

Delta import task Changes on Google Drive

Update changes or additions to OneDrive files and folders since the last import, including:

  • File names
  • File data
  • Modifications to file users or sharing permissions including additions or removal
  • File metadata
 Updates imported to files in Google Drive
Update permissions or user deletions from sharing lists Updates imported to files in Google Drive
Update deleted Dropbox files and folders Previously imported files and folders aren't deleted in Google Drive

What if I edit the list of folders I'm importing?

If you change the CSV file that lists your imported personal and team folders before before you run a delta import, the data import tool makes the following updates:

  • Add a user or team folder path to the CSV file—The folder imports to Google Drive.
  • Delete a user from the CSV file—The folder isn't included in the import, but any files or folders that already imported to Google Drive remain unchanged.

What happens if I update my identity map?
