Sun Java Communications Suite 5 vs 6U2

Today is my delivery completion day in Philippines for the Sun Messaging Server Upgrade Service for a local government agency.

During a brief transfer of information (TOI) session yesterday, I was asked what is the major difference between Sun Java Communications Suite 5 and 6U2.

I think I can best differentiate the both by using diagrams:

Sun Java Communications Suite 6U2 Software Architecture

Sun Java Communications Suite 5 Software Architecture

The software architecture in Comms Suite 6U2 has been simplified - Sun Java System Access Manager has been removed. The Delegated Administrator no longer needs to communicate with Access Manager in order to manage users' profiles that reside in the Messaging and Directory Server.

This is a big relief to many invoice administrators as they find installing Access Manager a nightmare.
