Hello All,
As we are running out of service/support from IBM for the WMQ and WMB 6.x versions, we have planned to migrate them to V7 version.
Being this kind of task is new to me, I have raised a PMR with IBM for the info reg this and got some URLs to go through, but OMG there are so many links and each is calling some other links. 
Have gone through most of those links and got some info regarding the migration tasks. But I still feel that I might have missed something which may be fatal. So, thought of posting my observation and open points here. (I always follow mqseries.net for all my doubts, because the replies here are so fast and accurate most of the time..  )
May be my doubts are weird and high level, but request you to please provide me with the details.
As per my understanding the tasks involved in migration are as follows.
1) Stop all MQ components ( queue managers, brokers, configuration manager) (MQ Admin)
2) Stop all DB2 instances (DB2 team)
3) Copy WMQ V7 install files to server (UNIX team/ MQ Admin???, Where is it available)
4) install WMQ V7 (UNIX team/ MQ Admin???, do we have to uninstall the old version(not reqd I suppose))
5) migrate queue managers (MQ Admin) ( anything else reqd????)
6) Copy WMB V7 install files to server (UNIX team/ MQ Admin???, Where is it available)
7) install WMB V7 (UNIX team/ MQ Admin???, do we have to uninstall the old version(not reqd I suppose))
8 ) Start queue managers and brokers.
We have 3 queue managers and 3 brokers (dev, integration and UAT) in one solaris server, so how can we migrate one instance after the other??
Do we have to modify any of the file(s) after installation/ during migration. If so, please let me know the list of those.
I'm still in the initial stage of the R&D for migration, so i may have to seek ans for so many in future...
If possible, a step by step approach would be of great helpful for me.
Thanks in advance.

Available from wherever you usually obtain it - speak to whoever deals with your IBM license.

AFAIK on UNIX you do have to uninstall. If I could be bothered to read the relevant QB guide I'd know....

Just migrate

See point 3 & I'd have all the install files on the server before you start.

See point 4 regarding manuals, except that I believe WMBv6 & WMBv7 can coexist.

See above regarding coexistance or not.

I'd start with those steps. Putting a full file system backup at step 0.

Thank you very much for the prompt response.. this is why I like mqseries.net
just a small doubt here..
steps 3,4, 6 and 7 :

Thanks again Vitor. |

Broker v6 and v7 can coexist.
The action of "migrating" a broker to v7 is done by issuing mqsistart from a command shell that has the v7 profile applied.
It is *simpler* to uninstall v6 and install v7, if you do not actually NEED to coexist your brokers.
And it would be a good excuse to take the time now to create scripts that build your v7 environment - queue managers and everything. Then you have these for any later need. |

Anyone can copy anything. If you need to copy it somewhere specific / useful you may need higher (or root) access.
You'll need root access to install anything.
If this means it's done by the Unix team or if root access is granted to the WMQ admin team for the duration of this exercise is a question for your site management, site security team, site audit team, etc, etc.
Enjoy.

| WMB 6.1 is not out of support or even approaching it. |

Granted, but if you've got a maintenance window and management support you might as well now as later.

| WMB 7 is fairly new, so it's a case of "Do you feel lucky?" - well do you? |

WMB v7 also has a lot of features that are unavailable at other levels - like a FileRead node. |

If the OP's management have bought into the upgrade clearly they do. Or given that the server in question doesn't run production feel the risk is managable. Or see this as the start of a good long run up to the production upgrade.
Or want to use some of the new v7 features.

As you are moving from MQ V6 to MQ V7 you might want to read the WMB pub/sub migration guide from MQ V6 to MQ V7...
Have fun

Friends,
Here I have one more doubt...
When I was googling or searching in forums or links provided by IBM, I observed that it is always better to clone the existing environment, install and migrate the cloned instance, test the working and then finally implement the same in PAT and PROD.
But my doubt here is, how is it possible to test the working of the migrated version as many other applications out of MQ server are using it.
Regards,
Harish |
