You need to step upgrade through major versions (not minor).
So 19.05=>20.x
I would highly recommend going to 21.08 while you are at it.
I just did the same migration (although they started at 18.x) with no
issues. Running jobs were not impacted and users didn't even notice.

Hi
I'm looking at upgrading our install of slurm from 19.05 to 20.11 in
responce to the recenty announced security vulnerabilities.
I've been through the documentation / forums and have managed to find
the answers to most of my questions but am still unclear about the
following
- In upgrading the slurmdbd from 19.05 to 20.11 do I need to go
through all the versions (19.05 => 20.2 => 20.11)? From reading the
forums it look as though it is necesary

However if that is the case it would seem strange that SchedMD have
removed 20.2 from the downloads page (I understand the reason is that
it contains the exploit) if it is still required for the upgrade.
- We are running version 5.5.68 of the MariaDB, the version that comes
with centos7.9. I've seen a few references to upgrading v5.5 but
they were in the context of upgrading from slurm 17 to 18. I'm
wondering if its ok to stick with this version since we're already on
slurm 19.05.
Any help much appreciated.
