I did install a new server ARC-CE with slurm-20.x
I installed only one node for testing.
On my old nodes I do have slurm-17.x
Now I am asking, if I am going to move my old nodes to the new sever
with slurm.20.x do i have to remove old slurm and install the new one,
or the two version can function together?
You may upgrade at most by 2 major versions of Slurm. For example,
17.02 to 18.08, then 18.08 to 20.02. I have collected information about
this in my Wiki page:

Upgrading of the Slurm database must be done really carefully as
described in this page.
