Ways of migrating existing data

Please, answer some short questions which should help us to understand your problem / question better?

• Which image of the operator are you using?: registry.opensource.zalan.do/acid/postgres-operator:v1.10.0
• Where do you run it - cloud or metal? Kubernetes or OpenShift?: on premise vmWare Tanzu Cluster
• Are you running Postgres Operator in production?: yes
• Type of issue?: question

What are the best ways to migrate existing data into a new cluster? So far we connected to one cluster pod and used pg_dump/pg_restore from the original cluster.

I think, the s3-clone option is thought to be for clones that originate from a cluster also previously managed by the operator, right? (You can probably augment a basebackup from an existing cluster so it works for the s3-clone, but that's not the main focus)

Is there a way to put existing dump files somewhere that will be imported upon first startup or something?

Thanks.

Start with the operator's s3-clone configuration and the cluster first-startup/bootstrap flow, then compare those with the pg_dump/pg_restore and basebackup approaches mentioned here. Document which migration paths are supported for existing PostgreSQL data and whether dump files can be imported automatically; the issue is complete when the supported procedure and limitations are clear.
