Hi Jason,
Slurm upgrading should be pretty simple, IMHO. I've been through this
multiple times, and my Slurm Wiki has detailed upgrade documentation:
https://wiki.fysik.dtu.dk/niflheim/Slurm_installation#upgrading-slurm
Building RPMs is described in this page as well:
https://wiki.fysik.dtu.dk/niflheim/Slurm_installation#build-slurm-rpms
I hope this helps.

Thank you for being such a helpful resource for All Things Slurm; I
sincerely appreciate the helpful feedback. Right now, we are running
20.02 and considering upgrading to 20.11 during our next maintenance
window in January. This will be the first time we have upgraded Slurm,
so understandably we are somewhat nervous and have some questions.
I am able to download the source and build RPMs successfully. What is
unclear to me is whether I have to adjust anything in the slurm.spec
file or use a .rpmmacros file to control certain aspects of the
installation. Since this would be an upgrade, rather than a new install,
do I have to adjust, e.g., the --prefix value, and all other settings
(X11 support, etc.)? Or, will a yum update "correctly" put the files
where they are on my system, using settings from the existing 20.02 version?
We purchased the system from a vendor, and of course they use custom
scripts to build and install Slurm, and those are tailored for an
initial installation, not an upgrade. Their advice to us was, don't
upgrade if you don't need to, which seems reasonable, except that many
of you respond to initial requests for help by recommending an upgrade.
And in any case, Slurm doesn't upgrade nicely from more than two major
versions back, so I'm hesitant to go too long without patching.
I'm terribly sorry for my ignorance of all this. But I really lament how
terrible most resources are about all this. They assume that you have
built the RPMs already, without offering any real guidance as to how to
adjust relevant options, or even whether that is a requirement for an
upgrade vs. a fresh installation.
Any guidance would be most welcome.
