How to failback to Original Writer instance after Upgrade

0

Currently i have 1 writer and 2 reader instance in AuroraDB. When I was trying to change the instance write instance type to larger instance, aurora automatically promoted a reader instance to writer. But after the upgrade finish, the original writer instance stayed as reader instance. Is there a way to have a automatic failback to the original writer after the upgrade is completed?

Unfortunately, no. The upgrade is designed to failover first to reduce downtime. The readers and write should be on the similar instance class in Aurora cluster. You can try either of these:

  • Upgrade your new writer now, which would automatically failover to give your original configuration with both instances to new instance sizing.
  • Manually failover the cluster to switch the configuration from console, CLI or API call, and then you can upgrade reader without a failover.
