Hi -
Here are some minor incidents we encountered:
1. This looks like a critical error, but it is a failure to add the Unity server to the local Internet zone. We already had the Unity server in Trusted Sites. The error looks like - Addunityrealm.exe, common language runtime - Application generated an exception that could not be handled, process id = 0x1564 (5476), thread id = 0x17cc (6092)
2. On one of 3 servers, the ciscopca did not install correctly, specifically the TOMCAT service was not installed. I worked with TAC on this. Because the PCA/TOMCAT service is installed with a combination of *.jar files, the only way we could determine to reinstall was to reinstall Unity. This time it installed correctly. No problems with the other two servers and we were unable to pin down as to why this happened.
3. DCOM Event 10016 errors in event log. Unable to access PCA - I fixed this by going to Component Services MMC on each Unity server and gave the Everyone Group Local Launch and Local Activation to the following: AvLic, AvCsGateway, and AvDsGlobalCatalog.
4. Not an upgrade thingy, but if you are planning to use the new 4.2 features, such as Alternate Contact number, we added steps into our upgrade process to update all subscriber templates for this new Caller Input Key and ran Bulk Edit to edit existing subscriber accounts.
Best wishes for your upgrade :-)
