After you successfully migrate all of your phases, you’re almost ready to go live in your new Google Workspace account. Before you complete your migration to Google Workspace, you need to migrate any recently added or modified content. You can transfer the new content by running a delta migration.
What's a delta migration?
A delta migration is run after the main migration, just before you’re ready to transition to Google Workspace. It identifies new or modified content and migrates the content to the target account.
Running a delta migration on an existing bridge is more efficient than creating a new bridge. A new bridge can create a significant load on target APIs and might result in a slower migration.
A delta migration is different from retrying failures. If you retry failures, Google Workspace Migrate makes a new attempt to migrate items that didn’t migrate on a previous run but it doesn’t check for updates to the source data. Delta migrations include a step to retry failed transactions, so if you run a delta, you don’t need to also retry failures.
For details, go to Retry failed transactions.
Make sure you use the same bridge for migrating data.
- In the Google Workspace Migrate platform, click Bridges. You might have to click Menu first.
- On a bridge that you have already run or partially run, click Run Run delta.
