Migrating problems from openbsd to kubernetes


I moved to a new server with Kubernetes. I copied data folder, imported database, I can see user information and channels (only if I search for, not showing in the sidebar), I have a problem with the text, not showing correctly.
I had version 5.27 in OpenBSD, now I have the current version, bringing data and db.
How could I have a functional mattermost version? What about db collation? How is the best migration to get to the current version and don’t lose user information and channels?

Thank you.

Hi dlgregory and welcome to the Mattermost forums!

You cannot directly upgrade from 5.27 to 7.4.0, you need to upgrade to the latest 5.x release first. If you do not do that, you will have some database migrations missing which could cause the problems you’re seeing here.
What database server in what version with what collation on the databases/tables are you running on the 5.27 deployment under OpenBSD?
