[slurm-users] upgrading slurm to 20.11

[byron]

Thanks Brian for the speedy responce.

Am I not correct in thinking that if I just go from 19.05 to 20.11 then
there is the advantage that I can upgrade slurmd and slurmctld in one go
and it won't affect the running jobs since upgrading to a new major release
from the past two major releases doesn't affect the state information.  Or
are you saying that  in this case (19.05  direct to 21.08) there isn't any
impact to running jobs either.  Or did you step through all the versions
when upgrading slurmd and slurmctld also?

Also where do I get a copy of 20.2 from if schedMD aren't providing it as a
download.

Thanks
