Exactly. Just upgrade the slurmdbd before anything else.
You should be able to upgrade slurm on your compute
clusters without losing any jobs or other state.

There was a patch to SLURM v2.2 to support secondary groups.
What is the upgrade path from 2.1.0 to 2.2? I saw notes about updating
slurmdbd first but is it as simple as just shutting down the old
slurmdbd and starting the new version or is there some migration of
the db data/schema?
I am not aware of any current problems in supporting the
AllowGroups functionality.
The following patch can be used to list the uids in each of the
groups listed in an
AllowGroups parameter. That should help to show you what is happening. Note
that the code in this function has several different paths for
various operating
systems (AIX, Sun, OS X, Linux), so there might be some issue in support of
your particular OS.

Subject: [slurm-dev] AllowGroups
I remember seeing a bug about AllowGroups and secondary groups prior
to the 2.2 release. Is the AllowGroups functionality completely broke
in previous versions? I'm running 2.1.0 and no matter primary group or
not I can't make this work. Every attempt gives me
srun: error: Unable to allocate resources: User's group not permitted
to use this partition
even thought the user has only one group(but the left over PAG id from
afs shows as a group) and the AllowGroups is set to that users gid.
