Hi All,

I would like to know your inputs on how to move existing MQ full repository queue manager into new hardware queue manager (New MQ Full Repository Queue Manager name is different).

Present MQ cluster Full Repositories queue manager name is CPQM1 and CPQM2 on WebSphere MQ Version 7.0 on AIX Operating System
Present MQ cluster - There are 8 MQ partial repositories queue manager to interconnect with CPQM1 and CPQM2 (4 PR QM interconnect to CPQM1 and other 4 PR QM interconnect with CPQM2)
New WebSphere MQ Full Repositories Queue Manager name CPQMFR001 and CPQMFR002 on WebSphere MQ 7.5.02 on AIX Operating System

Note - New WebSphere MQ Infrastructure Full Repositories queue manager names are different than existing MQ full repositories.

As MQ Infocenter best practices, we have to perform below task activities to add new MQ full repositories queue manager in the existing MQ cluster and remove existing MQ full Repositories :-
Create a new queue manager on MQ 7.5 Environment on AIX platform
Make a new queue manager as full repos on MQ 7.5 on AIX
Add new mq full repositories queue manager into the existing MQ cluster environment in aix environment.
Ensure that all queue manager cluster objects count sync with old mq full repositories (CPQM1 and CPMQ2) as well as new mq full repositories (CPQMFR001 and CPQMFR002)
At this moment, there will be no partial repository queue manager connect to new MQ full repository queue manager CPQMFR001 and CPQMFR
Ensure that new hardware MQ full repositories CPQMFR001 and CPQMFR002 are visible into all Full Repositories as well as into the partial repositories queue manager.
There will 4 MQ full repositories queue manager in the MQ Cluster and will ensure that all four QM FUll repositories are sync with each other with all MQ cluster objects

Remove CPQM1 and CPQM2 full repositories from the MQ cluster so there will be CPQMFR001 and CPQMFR002 full repositories queue manager available in the MQ cluster
Steps will be follow to remove CPQM1 and CPQM2 full repositories from the MQ cluster :-
1) Alter CPQM1 full repository queue manager to be a partial repository (alter qmgr repos(' ')
2) Suspend CPQM1 Full repository queue manager from the MQ cluster (suspend qmgr cluster(clustername)
3) alter cluster receiver on CPQM1 to take it out of MQ cluster (alter channel(channelname) chltype(clusrcvr) cluster(' ')
4) stop channel of CPQM1 from the cluster
5) delete channel of CPQM1 from the cluster
6) Verify that CPQM1 queue manager are not visible into the CPMQ2, CPQMFR001 and CPQMFR002 full repositories queue manager
7) alter cluster sender to CPQM2 full repository queue manager to be partial repository (alter channel(channel name) chltype(clusrcvr) cluster (' ')

stop channel and delete channel

Note :- At this point cluster has only three full repositories CPMQ2, CPQMFR001 and CPQMFR002 and CPMQ1 is out of cluster.
All partial repositories will be able to function as they have established connection to remaining full repository queue manager.

The same step will be perform to remove CPMQ2 full repository queue manager from the MQ cluster.

Question :-
RESET cluster command need to be execute on remaining full repositories queue manager CPMQ2, CPQMFR001 and CPQMFR002 to take all info about CPMQ1 queue manager from the MQ cluster out?
I think RESET cluster command need to be execute when you have same FR queue manager name on existing MQ cluster and new hardware queue manager full repository?
Is there any steps has been skip as per the best recommendation practice to remove existing MQ full repository and join new MQ full repository from new hardware?

Kindly provide your inputs on this.

Thanks,
MacWag
