You should be able to upgrade 2 Slurm major versions in one step.  The 
18.08 version is just about to become unsupported since 20.02 will be 
released shortly.  We use 19.05.5.

I have collected a number of upgrading details in my Slurm Wiki page:

You really, really want to perform a dry-run Slurm database upgrade on a 
test machine before doing the real upgrade!  See

We use the default MariaDB 5.5 in CentOS 7.7.  Upgrading to MariaDB 10 
seems to have quite a number of unresolved installation issues, so I would 
skip that for now.  Se s

Slurm 19.05 works great for us.  We're happy with our SchedMD support 
contract.
