| Can anyone please briefly run through the pitfalls and things to be aware of in upgrading WMQ in a Veritas Cluster? I can't find any support documentation or references to this in the manuals. Support pac MC6A applied. |

Nothing special...
- Bring down MQ normally (so it won't fail-over) on Node X (where it is running)
- Backup your data...
- Upgrade MQ on Node X
- Bring up MQ on Node X, see if it runs ok...
- on Node Y only upgrade MQ software (data is already migrated on Node X)
- Failover to Node Y, see if that is running properly
- Failover back to Node X...
When using MQ clustering (not HW/Veritas clustering...), there is a pmr1908 (on CSD4) that is not yet in a CSD as there are some time-out problems that cause runmqsc to hang...

the full pmr number is 01908,411,788 and fixes a problem introduced in CSD3 when fixing defect 7223 hung amqrrmfa.
If you are not implementing 5.3 CSD3 or above or not using MQ clustering... don't worry about this problem...

| Sounds like you did this procedure without stopping VCS - is that true? |

I don't recall any VCS specific commands...
I guess the whole point is not to 'upset' VCS in thinking that it needs to fail-over when you bring down MQ on the first node...
