[slurm-users] Upgrade from 17.02.11 to 21.08.2 and state information

[Brian Haymore]

Are you running slurmdbd in your current setup?  If you are then the upgrade path there might have additional considerations moving this far in versions.

The "Upgrades" section of the quick-start guide [0] warns:

> Slurm permits upgrades to a new major release from the past two major
> releases, which happen every nine months (e.g. 20.02.x or 20.11.x to
> 21.08.x) without loss of jobs or other state information. State
> information from older versions will not be recognized and will be
> discarded, resulting in loss of all running and pending jobs.

We are planning for an upgrade from 17.02.11 to 21.08.2. 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?
