Yes, we are running slurmdbd. We could arrange enough downtime to do an incremental upgrade of major versions as Brian Andrus suggested, at least on the slurmctld and slurmdbd systems. The slurmds I would just do a direct upgrade once the scheduler work was completed.

As a part of our upgrade procedure we'd be bringing the scheduler to full stop, so the loss of running and pending jobs would not be a concern. Is there anything more to state information than running and pending jobs? For example, would the JobID count revert to 1 in the case of such an upgrade?
