Beware: You can as a maximum upgrade only by 2 Slurm major versions!
This is well known, see a summary in 
https://wiki.fysik.dtu.dk/niflheim/Slurm_installation#upgrading-slurm

All data in your database will be migrated correctly to the new Slurm 
version.  This assumes that your upgrade process worked without errors! 
Older MySQL versions may have problems!

Therefore it is critical to first test the database upgrade on a test 
system!  Please see the above page for advice on the upgrade testing.
