What You Need to Do

No action is required from customers or administrators. All affected applications will automatically return to full operational mode once the migration for the applicable region is complete.

Customers are advised to:

  • Plan operations accordingly — Avoid scheduling tasks that require write operations or data updates within affected applications during the designated maintenance window for their region.
