HI. I’ve done several installations in native form as well as podman. Sadly never any migration. How to do this?
The current setup is a Debian 11, nextcloud 27, php 8.0, postgresql 13 and I want to move this over to a podman installation:
docker.io/library/postgres:15
docker.io/library/redis:alpine
docker.io/library/nextcloud
My problem is that I have no idea how to do this. Do I need to setup the podman installation first, copy the old data dir to the new data dir and dump and import the database? What user should I set up as admin user, the same as in the old installation or will this conflict?
Also: Whenever i do migrations I also try to keep the database versions aligned (it should go without saying that you should keep the NC versions aligned!). Even if I plan to upgrade the DB, I do it after the migration is successful.
Doesn’t matter because you’re going to drop the database on the target installation just before you import the db dump from the source installation.
P.S. I recommend appending a version tag to your nextcloud image as well. At least a major version tag, if not a minor one (though I prefer minor so I can control upgrades fully).
