upgrade to VirtualCenter 2.5 U6 from U4 stopped VirtualCenter Server, why??

[tlyczko]

Yesterday upon trying to upgrade VirtualCenter 2.5 from U4 to U6, the result was that the VirtualCenter Server service refused to start, showing the famous error 2.

I added the SQL Express dependency but this did not work, and I had to roll back to the previous night's backup.

I did not receive any error messages during the process.

Should I do U4 to U5, then U5 to U6??

So far as I could tell I followed the instructions correctly, I chose to keep the existing database.

Thank you, Tom

Solved by watching this video:

Important to stop the Web Access service and have DSN logins on hand.

Only thing is that Help/About says the build number is 227637, and VMware's site says the build number is 227666????????????

Thank you, Tom
