I am going to keep editing this post till I am satisfied I have recorded all I have experienced
Good things
Server Installation seems to not have any issues
The web application seems to run much faster
A good hardware or VM environment makes all the difference
Windows AD Kerberos SSO sign-on documentation works perfectly if you follow it EXACTLY !
History Screen Auto-Refreshes in CMC and launchpad
Not so good things
Tomcat has had trouble stopping
There are more warning messages in the event viewer that are not necessarily things you can fix
RAS server can have issues that cause it to restart
Connection server uses 64 bit ODBC
Migrated Crystal 2011 Reports use 32 bit ODBC
Client installation works on Vista 64 (did take 3 different times to get it working and then my MS Office 2007 got wacked)
Error messages are not any better
Migration specific issues
If a user set their Web Intelligence settings to the Webi (Interactive ) Viewer for their default “modify” option then when migrated in 4,0 it shows “Interactive Analysis” and they can only view reports as the query builder does not seem available in the “Interactive Analysis” viewer. They need to change it to the Rich Client (i.e. Java viewer)
Upgrade Manager doesn’t act the way you would expect around importing groups and changing the dependency menu once you have expanded the users and groups screen can crash it
