We have currently version 18.08.7 installed on our cluster and want to
upgrade to 19.03.3.. So I wanted to start small and installed it one of
our compute node. Buy if I start the 'slurmd' then our slurmctld will
complain that:
{{{

}}}
I have read about the RPC protocol:
* https://slurm.schedmd.com/rpc.html
Can an old `slurmctld` not communicate with a newer `slurmd`? Or is this
setup supported and something else goes wrong?
Regards
