Yes. You can build the 8 rpms on 9. Look at 'mock' to do so. I did
similar when I still had to support EL7
Fairly generic plan, the devil is in the details and verifying each
step, but those are the basic bases you need to touch.

I just finished migrating a few dozen blade servers from torque to
slurm. They're all running Alma 8 currently with the slurm that is
available from epel. I do want to get it all upgraded to running Alma
9 and the current version of slurm. Got one system set up as the
slurmctld system running Alma 9. I grabbed the tar ball and built
RPMs for 9.x. Got a few questions about the best path to proceed.
Can I use the Alma 9 system to build rpms for Alma 8? I'm sure I can
rig up an 8 system to build rpms on but thought I'd see if there was a
way to do it on the one 9 system.
My plan will be to get the rpms built for 8 and 9, update the
slurmctld system to the latest version of slurm, then update all the
nodes to the current slurmd version. Once that's done I should be
able to reinstall individual nodes to Alma 9 and the same version of
slurmd.
Am I missing anything in that sequence? I'm fairly confident that the
users aren't running any code that will notice the difference between
a node running 8 or 9, that should be transparent to them.
