FAQs About Migrate Data and True-Up Data

Q: What's the difference between Migrating Data and running a True-Up?

A: The first time you run a fresh migration job where no data exists on the destination, Migration App copies the data from the source to the destination. Any subsequent data migration is a True-Up, and you can re-run True-Up Data multiple times.

 

Q: What happens when I run a True-Up?

A: Migrate Data and True-Up Data metacommands operate differently.

When you run Data Migration:

  1. It first scans the source.
  2. It will then check to see if each file on the source exists already on the destination. If the file does not yet exist there, it will be copied to the destination.

When you run a True-Up, which synchronizes or mirrors the source and the destination, it does so through a five-step process:

  1. It first scans the source.
  2. It then scans the destination.
  3. Next, it compares the source and the destination to build a table of Deltas - anything that's new, deleted, or has been changed on the source.
  4. Next, it migrates the Deltas to the destination.
  5. Finally, it deletes any files on the destination that no longer exist on the source. This action is called "Syncing Deletes" and is an important action to be aware of.

Note that only during Step 4 does the Migration Job dashboard provide an estimated time of completion. This may be confusing since the command can run for an extended period without showing any progress. 

 

Q: If I run a True-up, does it create duplicates of what was already copied previously?

A: No.  A True-Up simply mirrors the Source and the Destination.  It copies anything new or changed the Destination, and removes anything from the Destination that no longer exists on the source.

Q: For a True-Up, what explains the discrepancy between the amount of data scanned on the source versus the amount of data migrated?

A: When you do a True-Up, only the deltas will report as migrated. For example, you might have 90GB on the source, but only 10GB is new or changed. So only 10GB needs to be migrated as part of the True-Up process. The progress bar on the UI provides some indication of how much data has already been migrated vs. what is being migrated as part of the current command.
