Currently, we have two pods running on volumes with a standard StorageClass. We want to migrate these volumes to a new high-performance StorageClass (high-speed) without causing any service downtime.
We attempted to create a third temporary replica with the new StorageClass and performed a switchover of the leader to this new replica. However, when we reduce the number of instances back to 2, the new instance, even if it is the leader, gets deleted and the old PVC/PV with the old StorageClass are still being used.
What would be the best way to migrate our volumes to the new StorageClass without data loss or service downtime, please?
