CloudMigrator can perform delta migrations for all source and destination platforms, but there are some important differences when migrating files to Google Drive and One Drive.
Delta migrations of files to Google Drive and OneDrive will migrate any new files that we were not found as part of the previous migration(s), but will also detect if files have been modified or updated since the last migration. Files or folders that have been edited, have had permissions changed, have been renamed or otherwise changed will be re-migrated and the file or folder in the destination deleted and re-migrated. This results in a new destination document or folder ID.
Due to limitations of the API and platform, there are a couple of considerations when performing delta migrations of renamed and moved folders to OneDrive:
- From Google Drive, OneDrive and Box – folder renames or moves are ignored on delta migrations
- From File System – renamed or moved folders are treated as new folders and migrated, along with their contents to the destination
