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

[Nathan Smith]

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?
