Restoring db from Immich docker into Immich LXC

[Inderix]

Hello, bit new with working with databases and seeking help with how exactly to handle this.
I'm moving data from a broken and now gone CasaOS system with Immich to a shiny new Proxmox-based setup. I managed to recover the upload directory from the old instance, but I'm a bit stuck on how to move it into the LXC correctly. I've combed over Immich's docs for this, but I'm a bit over my head on what I'm looking at here.

I have a bunch of .gz files in /upload/backup from the old instance as well, the latest one decompressed into a .sql file, I imagine this is a database dump. I've already created an LXC using the immich community script. To be clear I'd like to use the default /opt/immich/upload directory, since the LXC is created on a very spacious drive, I just need a bit of a push in understanding postgres and how to perform the database import.

As for posts similar to my issue:
I've read over #5075 however its not clear to me what applies to my situation.
#5384 - my LXC instance seems to be missing the "postgres" command, I am unsure how to work around that.

in short; i am stupid and lost :(

I'm humbly coming to this community in hopes for an "explain it like im 5" kind of approach to getting this move in complete, I have some command line experience, I promise, I was just terribly unprepared for what I'd be getting into with Docker and database management.

Welcome @Inderix 😄

You're not the first one to ask for a guide related to this, since starting over can be painful if you're coming over from Docker. Before the helper-script was out, I had a patchwork LXC of Immich that I had cobbled together, and I wanted to switch to the script version while restoring the DB and using the Immich library I already had. But while I believe I did the DB restore just fine, I couldn't get the new Immich to see the library, and I eventually gave up and exported all the photos from the old library and re-uploaded them to the new.

I believe what you want to do is possible, I just haven't ventured to try again lately, especially since simply keeping up with the script changes takes up so much time as it is. It is something I plan to tackle eventually, though.

If anyone out there has already managed this, they are more than welcome to create a guide for it!

In my case, with how many albums and the sheer number of photos/videos in the library uploading and manually re-organizing them really isn't too great of a choice due to the circumstances of the old server pretty much imploding. I would greatly appreciate a written guide showing how to import a db backup from a Docker instance into an LXC script instance.

Found this project: https://github.com/epichfallen/ImmichSafe

don’t have time to check it out right now, anyone want to take a look?

This will only work on the Docker version of Immich:

Ok, we can ignore it 😞
