Migrate from NC 22 Snap to NC 23

Looking for some advice on how to move user files from a VM running NC 22 in a Snap installation to a new VM running NC 23 that was installed manually. Both are using LDAP to AD for user information.
Both are running Ubuntu 20.04.

However, NC 23 is setup with some apps and other settings that I changed from 22. For example, LDAP users on 22 were brought over with their SID. Users on 23 were brought over using the sAMAccount name.
So, I’m not sure a DB backup and restore will work.
I really only need files as we don’t use NC for anything more than file storage/access.
