Hello
Client is on ECC 6 and wants to upgrade to ECC 7 EHP. The ECC system interfaces with many other systems. Client told batch programming interfaces also are there. Many systems involved to ECC.
The legacy sytems that are compatible with ECC 6 should not have any problems with ECC 7 right?
For the effort estimation what all should I ask?
I have to clarify if PI is upgraded plus what other questions should be asked to calculate the effort estimation for PI
