Hi,
Is there a white paper on how to upgrade IBM MQ 5.3 to 7.0 ? Or is it possible in the first place ?

Depends.... the big question is do you need to keep messages in queues while doing the upgrade or not?
Delete and rebuild might be the fastest way for you.
Depending on your circumstances you might need to go
5.3 -> 6.0 -> 7.0.0 -> 7.0.1

Actually we want to add a new MQ 7.0.1 to an existing MQ Cluster of 5.3. Than after sometime add another 7.0.1 Queue Manager making it four. After that remove the old ones to only have QM 7.0.1 in the Cluster will that be possible ?
Thank you. |

IBM advice is to have your FR's at the latest version, i.e. upgrade them first. If doing that is not possible, consider building a 'parallel V7.0.1' cluster where that cluster's FR's are at 7.0.1 (your new queue managers), join your V5.3 queue managers to it as PR's, and the V7.0.1 queue managers to the existing 'V5.3' cluster as PR's, not forgetting to namelist queues etc. Once you have everything in place, de-namelist the queues and decommission your original V5.3 cluster.

Hi,
That is somehow what we are planning. What about adding a Queue Manager 7.0.1 to the existing Cluster and making that one as well as FullRepository ? What drawback exist there ? I want to add two new Queue Managers on different machines with MQ 7.0.1 making them too FullRepository. After that I will remove the old ones ?
Thank you. |

Are you sure they really need to be in the same cluster at the same time?
Can you not just build them, create a new cluster, and then move the apps to it?
If you really had to do this, I would still create a new cluster and then add the old qmgrs to it as PRs, rather than add the new qmgrs to the old cluster. |

Do not have more than 2 FRs in a cluster at any time. So once you've added a v7 queue manager as an FR, demote one of the existing ones (there's no need to remove it from the cluster unless you have a business or design reason; it can sit as a PR for as long as you need)

We have a cluster with about 70 members (AIX and Windows) and have upgraded about 30 of them so far from 5.3 to 7.0.1 without any issues at all (did the FR's first). We just followed the documentation that PeterPotkay mentioned earlier.
