Slurm users,

I'm planning on moving slurmctld and slurmdbd to a new host. I know how 
to dump the MySQL DB from the old server and import it to the new 
slurmdbd host, and I know how to copy the job state directories to the 
new host. I plan on doing this during our next maintenance window when 
there are no jobs running on the cluster.

However, there will be plenty of jobs in the queue, so my question is 
this: What will happen to jobs in the queue when I do this? Is the queue 
information stored in the database or the job state directories, or a 
third location? How can I make sure I don't lose the state of the queue?
