Hello all,
What I will ask, maybe it seams crazy for a part of you.
We have to upgrade urgently the OS where the MQ servers are installed.
Currently we use windows 2000, and MQ 5.3. Urgently means 5 days (audit reasons).
We would like to upgrade to windows 2003 R2.
My question is, if we make an upgrade of OS, from windows 2000 to windows 2003, what is the impact of the MQ ?
We must reconfigure the MQ?
Can we save the settings, and after the OS upgrade, reinstall MQ 5.3 and put them back ?
May you will ask, why don't we migrate also the MQ to a newer version.
We have that in plan, but is taking longer than we expect.
We are preparing a migration of this MQ server to new ones, on version
6.2.xx, but that will be done in one or two months.
Our current configuration is that MQ is installed on the same server as the application.
On the new configuration, the MQ will be installed on separate servers.
Thanks a lot. |

That's the crazy part. If you're going to all the trouble of upgrading (maintenance windows, regression testing, etc) why not go to v7? Why go to something the auditors will insist you move off of in the foreseeable future?

What does the IBM site say about WMQv5.3 on Win2003?

Be sure and point out to whoever in management decided not to stay somewhere close to the upgrade curve that all this frantic activity could have been avoided with a measured, planned upgrade strategy.

Also, why go from one unsupported version to another, when you can just as reasonable go from an unsupported version to a supported version.
There is no MQ v6.2.xx either. There is only MQ 6.0.2.x.
And it goes out of support this year. |

Auditors insisting that you migrate from one out-of-support version of software to another out-of-support version is not a best-practice.
What reason have the auditors offered?
Remember, auditors cannot mandate anything; rather, they can raise an audit-item with management.

Maybe is crazy to move to a version that get out of support this year but is the only one that we can move on for the moment.
It was proposed from the new MQ support team.
They will install and configure this new MQ servers.
Currently for me this is the second crazy thing.
The current MQ servers are under our administration, and we are in charge to migrate them, until the next team will prepare the new servers and put them into production.
Unfortunate I cannot find a list (updated) with approved OS for MQ 5.3.
All links that I found from this forum are obsolete.
At least if I can found that the MQ version 5.3 is not supported on windows 2003, so we can close the case.
I did find some books, where it says that for MQ 5.3 the last OS version is windows XP.
But these are old books, and maybe there are some updates, and this version is supported on newer version.
Thanks a lot.
Later Edit:
I found that windows 2003 is supported for MQ 5.3.
I was hopping not to  .

Really? I asked Mr Google about "Websphere MQv5.3 system requirements windows" and he found this for me.

Why? What makes v6 easier to migrate to than v7 from v5.3?

I found something, also on IBM site.
Thanks for you link. Now I'm sure that windows 2003 is supported.
I don't know why they want to upgrade to version 6, but that is another problem. I will pop-up this to my management and they should decide this.
What should I do before OS upgrade?
Anything else then a full backup ).
And after OS upgrade?

Search google for mq v5.3 migration.

I would do that, if it was an MQ 5.3 upgrade, and for that I found a lot of information.
But for OS with MQ 5.3 upgrade, without upgrading MQ also i didn't find anything.
For MQ upgrade I see that IBM site has a lot of information and there a lot of posts here on this subject: http://www-01.ibm.com/support/docview.wss?rs=171&uid=swg21261359#w
I realize last night that our UAT machine is on windows 2003, which answer again to my question if MQ 5.3 is supported on windows 2003, and because the of this I cannot do a test there, which is bad news.

Be very careful with such a change. It may have consequences for the applications that do a 2 phase commit. Are you running the Extended Transactional Client (etc)?
And BTW, if I were one of your auditors I would insist on Server 2008... (Isn't win server 2003  obsolete already??)
Have fun

I'm forced to agree. Given all the circumstances. 
And my most worthy associate makes a very good point which I'd failed to pick up on. Moving the applications onto a separate server could break them if they're on the same server to allow the use of a bindings connection & the 2-phase commit (back when this software was new the ETC was an expensive & separate piece of kit).
You might want to get the application teams to check that before you just move stuff.

They'll break even if there is no 2 phase commit involved. At the very least they have to recompile with the MQ Client libraries versus the bindings libraries (unless they are Java), and somehow specify the remote MQ server details (start using channel tables, MQSERVER or change MQCONN to MQCONNX).

I think it still is, but don't quote me though!
