Was your data container a standard data container? I’ve been wondering if it would move just the one database or all of them in the cluster. It sounds like you’ve answered my question!

What I’ve been doing is hand moving each database from the old cluster to the new one, then hand editing discourse.conf to point to the new database and then doing a rebuild to point the whole multisite container to the new cluster (on a different machine or port).
