Upgrading slurmdbd from version 1 ================================= The 2.0 slurmdbd will work with SLURM daemons at version 1.3.7 and above. You will not need to update all clusters at the same time, but it is very important to update slurmdbd first and having it running before updating any other clusters making use of it. No real harm will come from updating your systems before the slurmdbd, but they will not talk to each other until you do.
