Going into hour 50 of our WB-IMB 5.0 upgrade weekend with just 3 hours of sleep. The people responsible for inventing MicroSoft Cluster Services are the spawn of Satan...... 
happy to say we are succesfully upgraded, and just hanging around waiting for all customer signoffs.
Any other horror stories about upgrades that went forever?
Where's the sleepy emoticon?

I might have to agree with you on this one.
Seriously, congratulations! |

Congrats Peter!
I wonder if you had a new server for the upgrade or did you install the product on the existing server.

I upgraded 2 Windows 2000 servers that were a Microsoft Hardware cluster from WMQI 2.1.5 to WB-IMB 5.0.4.
Fun stuff included the WB-IMB upgrade wiping clean the path variable on one node and inserting only its variables, causing the cluster resources on that node to become corrupted, the MAXAPPLs setting on the DB setting itself back to the default of 40 after setting it to Automatic (we double checked that one 3 times too), having left at 3AM Saturday after finally upgrading Node 1 to 5.0 only to be paged at 7 AM the next morning because the DB for Node 2 was completly shot, probably during the cluster resolution process, WB-IMB installing itself in folders that were specific to the 2.1 version, causing us to have resinstall, and not 5.0, and on and on and on.
Despite Microsoft's and IBM's best efforts to make this upgrade as difficult as anything we have ever done in the MQ world, we got the job done.
We are looking at changing our setup after this fiasco. I was never a fan of hardware clustering for WB-IMB brokers when we have 2 of them in a MQ cluster. I would rather spend the money and have 3 or 4 standalone brokers in a MQ cluster. Very unlikely that a message will be stranded on a server if I have 4 of them. If they insist on hardware clustering, then its an Active/Passive setup, not Active Active. The 2 servers in a MSCS cannot be treated separatly. They are a single entity in my opinion. Fiddling with one broker more than once screwed something up for the 2 broker. And trying to upgrade 2 brokers at one time is not something I would plan for, as it would take to long to be feasible. And we proved that. Thank god for Red Bull!
