Hi, we are migrating our pinot installation to a different region in gke. Has anyone done this before? Do you recommend shutting pinot down, creating snapshots and then redeploying in the target region? Also, the ip's of the kafka brokers and schema registry will change, is it possible to modify the table config to reflect that?

One way would be to bring up the other region first (with data ingestion pipeline setup as well). And then gradually move traffic out from one into another.

Nice, the only issue is that we will be using the same namespace and k8s cluster in gke. Would we be able to add nodes in the new region and then remove the old nodes?

Yes
