We are planning to migrate from MQ 5.3 on Solaris to version 6.
In the documentation of MQ it stated that you must uninstall the old version first.
To save the current objects of QMGR's and Q's, is it enough to backup /var/mqm ?
The only info about migrating MQ i found was about version 5.2 -> 5.3. And there they advised to backup /var/mqm.
Can i do the same for 5.3 -> 6? |

for whatever info i could find, i think backing up /var/mqm directory would be fine.
for more info visit
http://publib.boulder.ibm.com/infocenter/wmqv6/v6r0/index.jsp
and in the search criteria type
"Migrating to WebSphere MQ Version 6.0"
u'll get topic
"Migrating to WebSphere MQ Version 6.0 and upgrading your operating system
"
under which this is mentioned. |

I'm told some people also use saveqmgr (supportpac ms03) and "amqoamd -s" to backup their object and security definitions first (and regulary)

I have upgraded both Windows and AIX from V5.3 to V6. In both cases, the upgrade was done without removing V5 first. The install process converts the V5 system to a V6 system, preserving the objects, permissions, and messages in the queue.
Is the requirement to uninstall V5 first unique to Solaris ? |

On Solaris you have the problem, that the package name is the same and by default you cannot overwrite (yes, I know, you may use admin files ...).
On AIX and Windows it ist possible to upgrade, but I never do so.
I always de-install a previous version, before I upgrade. Nevertheless the objects, permissions and messages in the queue are preserved anyway.
BUT: I am a little bit paranoic, so follow vennela and backup the directory
/var/mqm. All QMgrs must be down.

for a windows migration upgrade from 5.3 to v6: for a fall back to 5.3 after migrated to v6. has anyone done this? I'm thinking about backing up the windows system files, the MQ install paths (binaries, logs and queues). also running saveqmgr. Thoughts regarding this?
tia.

For windows, if you have to fall back to 5.3, possible clean option would be uninstall V6 and re-install 5.3. This way, Registry entries would be clean. It would be interesting to see how the queue manager Data ( qmgr folders) respond to this. I guess they will not start as some of the data might be migrated to V6. In this case you need to rebuild your queue managers from previously saved definitions.
I would like to know if any one already did this ....

Yes, you should back up /var/mqm but that is really in case you need to go back to the earlier release, /var/mqm is not removed by uninstallation on Unix platforms.

Whenever we have upgraded versions on Windows (5.2 to 5.3 most recent), we've always backed up our object defs (with Saveqmgr) and security defs, but have never backed up the base MQ installation folders.
After unistalling the old version and installing the new version we recreate the QMgr and all objects and re-grant OAM using the backed up definition files.
It seems like some are implying that somehow the object definitions persist thru an uninstall - reinstall. If so, how is that accomplished?

Maybe you are uninstalling in a particularly destructive way. The Windows Uninstaller should not delete the qmgrs folder of your MQ installation, normally.

Yes indeed....once we run the Uninstaller, we manually blow away the installation folders in the file system - ensuring that all vestiges of the previous version are gone.
We thought we had to do this in order to ensure a clean re-install with the newer version!!!!
Guess we were wrong!

for windows migration v6, backout to 5.3- knowing that any work, messages in the v6 environment will be gone, having made backups; uninstall v6, restore the 5.3 installation path, the log path, the queue path (usually the same as the install path) the windows system files (registry).
how does this sound ? I'd rather not do an reinstall of v5.3. thoughts, comments?
thanks

There isn't much (any?) information in the Quick Beginnings - upgrade sections regarding clustering.....
Most of my QMgrs are part of a cluster, with 2 being full repositories, etc. Are there any "special" considerations when upgrading from 5.3 to 6 regarding cluster membership?
I have posted this question on the clusters forum, with no replies....

You want to upgrade your FR's first, so they can hold the v6 queue attributes (like clwluseq), then upgrade your PR's.....
