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.
