Recreate server admin

for some reason the main server admin got messed up. can’t create folders and cannot see or use existing datasources (logging as regular admin I can see them).

so I’ve deleted the server admin via sqlite cli and imported a new server admin from a fresh grafana installation.

If there a way to make an existing admin a server admin?
or, what does one do when the server admin is messed up?

I would like to avoid of installing it all over again.
