CUA upgrade from WAS 6.20 to NW 7
I have a requirement where we need to upgrade a system from WAS 6.20 to NW 7. The system is only being used for security purpose, i.e. only CUA is configured in that system for other systems - R/3, BI, SRM. I want to know what are the different we need to carry out after upgrade which are very specific to the security or CUA.
