Many programs find out they’re behind only when cutover is a week away, because they check progress right before cutover instead of throughout pre-stage.
Pre-stage duration is usually predictable if you measure real throughput early and use it to forecast the remaining passes:
- Use the first pre-stage pass as your baseline.
- When a representative batch completes, pull the BitTitan project export and calculate actual throughput in GB per hour.
- Compare that rate to the data volume still remaining for later passes.
If the numbers say you can’t finish before the cutover window, change something: adjust batch timing, reduce the concurrent job count to ease throttling, or move the cutover date.
The same tracking surfaces stalled accounts early. An account showing minimal data migrated after a full 24-hour pass should be investigated before cutover, not after.
Are you checking pre-stage throughput against your schedule at regular intervals throughout the pre-stage period?
