The DB migration at the end of this upgrade is significant, I was surprised how long it took when I upgraded my instance. Lots of room for things to go wrong considering the size of their DB.
That makes sense, especially how large the instance is.
Just curious, how long did the migration take for you? Half an hour?
10-15 minutes here on a 32gb database.
It took about the same for me.
Interesting, thanks
Took me the whole day. The new migrations require PostgreSQL version 15, and my Akkoma and Lemmy are using a shared database server of version 13. First shut down both services, then update Debian from 11 to 12, PostgreSQL from 13 to 15 and after all this, redeploy Lemmy to start the migrations. The new Lemmy queries use more RAM compared to the previous version, so the database was getting OOM and I needed to upgrade to a bigger instance.

Not fun, but everything works now and is stable.
