How to in Update process of SP's with Upgrade of Add on
I'm updating the system to the latest ECC 6.0 STACK 20.
This includes various SP's and also, in my case, a update of PI_BASIS (version 2005 to 2006).
My question is, should I update the PI_BASIS in SAINT to the SP0 of 2006 version, and then continue the update of the other components (HR, BASIS, FI, EA-HR, ...) on the SPAM and also the update of the 2006 version to the latest SP?
Or is there another way?
