Hello,
What is the step by step procedure of upgrading MQ Cluster?
is it:
1. suspend QM
2. stop QM
3. upgrade QM
4. start QM
Move to the next one.
Is it correct?
Thank you,. |

Rather depends on what sort of HA clustering is being used.
Failover to make it inactive first might be preferable.

Resume the queue manager back into the cluster as a last step before moving to the next queue manager.
Upgrade both Full Repository queue managers (one at a time) before upgrading the Partial Repository queue managers.

Thank you very much!
It's a cluster without multi-instance QM's. |

| Just remember to carefully document each step and test functionality after each upgrade to ensure stability. Also, depending on your environment and complexity, you might want to consider utilizing a tool to measure your progress, especially when repeating these steps. Speaking of tools, I recently used a CPS test to gauge my responsiveness and found it helpful for a different kind of project! Good luck with the MQ cluster upgrade! |
