It is only possible for Slurm versions in a cluster to differ by 2 major 
versions.  The 22.05 slurmctld can therefore only work with slurmd 22.05, 
21.08 and 20.11. The documentation is in 

My Slurm Wiki page explains the details of how to upgrade Slurm versions: 

Please note that the current version of Slurm is now 23.11, and that only 
23.11 and 23.02 are supported.  There are important security fixes that 
makes it important to upgrade to a supported version of Slurm.

I hope this will help you to make the upgrades.

Best regards,
