[keycloak-user] Promoting Realm and Client changes from dev to prod

I found some older threads on the mailing list about this, but I'm not sure I parsed out the proper answer. What is the best way to promote changes to KC realms and clients from dev to prod? I'm using kubernetes for prod and staging, and docker-compose for local development. I found the export/import [0] functionality, but it can only migrate a changed realm by first deleting the realm in the target database then recreating it. This has the side-effect of deleting all users in that database. The users in the prod realm will always be different than the users in the dev-env realm, so I can't delete the realm. Does this mean I can't use the import/export functionality to promote realm changes? I also saw mention of some "partial import" functionality, but I can't find docs for it. Would that help here? I also saw mention of a "config manager", but I can't find any docs for it. Perhaps the best way to migrate changes is to simply perform them by hand in each KC instance, and not redeploy it.
