I am upgrading slrum just on a worker node.
I drained all the jobs on the old slurm.
The only active service on my worker node is slurmd.service
Please read carefully the Slurm documentation:
The recommended upgrade order is that versions may be mixed as follows:
slurmdbd >= slurmctld >= slurmd >= commands
You cannot mix 20.02 with an old 17.02 or 17.11 Slurm!

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:
https://wiki.fysik.dtu.dk/niflheim/Slurm_installation#upgrading-slurm
Upgrading of the Slurm database must be done really carefully as
described in this page.
