I have this environment with 100+ DBs and would like to migrate to GCP's cloud SQL for Postgres.
Primary: 48 CPUs, 48GB memory
Secondary/Read Replica: 80 CPUs, 128GB memory
PG version: 12.22 (we have already started the upgrade process)
OS: Ubuntu
I would like to migrate 2 DBs first and a few more later. I was thinking of logical replication, but wanted to take recommendations if there are better approaches available. We cannot afford breaking the read replica due to our read intensive app connects to this node.
