What type of throttling will G Suite apply to my account?
G Suites uses throttling both when retrieving and pushing data. Throttling limits are different for retrieving data vs. pushing data.
Google may lock your account for 24 hours if they consider that too much data has been retrieved from their servers in a given amount of time.
If that occurs, we recommend pausing the migration and submitting a delayed migration (after 24 hours).
Also, G Suite imposes a hard limit of one (1) item per second when migrating to G Suite. MigrationWiz adjusts migration throughput accordingly, but remains subject to those limits.
You can find more information about G Suite throttling limits in the Google article Bandwidth limits for accounts.
