Hi,
We are planning to upgrade the MQ 5.3 servers to MQ7.0. We are having a MQ Cluster setup with FR and PR queue managers.
I am just thinking that before upgrading MQ do i need to suspend the FR and PR queue manager from MQ Clusters and then stop MQ? or simply stopping MQ and then perform upgrade will not affect existing MQ Cluster?
will I upgrade the PR queue managers servers before upgrading the FR queue manager servers?
Cheers,
Aditya |

Depends how paranoid your site is. I'd suspend them but I don't think it's essential if the maint window is small. Other opinions valid here of course.

No. Upgrade the FRs first, especially as you're moving from v5.3 so have the new clustering features to content with. Not so significant v6 -> v7, though I believe it's considered best practice to have the FRs on the highest level in your cluster.

right, in general, it is most certainly best practice to have the FR at the highest level in the MQ network when using clustering.
The other way is supported but only if you are that the current maintenance level and that is not likely for the older QMGR. So, rather then apply maintenance and then migrate, just migrate.
Start with the FRs. |
