Implications of SP upgrade from SP19 to SP 20
We are planning to upgrade our Netweaver Portal from Netweaver 7.0 SP 19 to SP 20. As we have other systems integrated with this portal, I want to knwo teh implication of this SP upgrade on other systems liek SRM, CRM etc.
The current scenario is :
Portal Netweaver is version 7.0 SP 19
SRM is on SRM 7.0
CRM is on version 7.0
BI is on version 7.0
Netweaver ABAP stack BIT is run with BW 7.01 (EhP1 SP 5)
Netweaver Java stack EAQ is run with BW 7.00.
Please let me know the best reccomended version of upgrade so that the existing systems like SRM, CRM and all wont be affected much. Also please suggest if along with the portal upgrade we will have to get these systems also upgraded of whether it will be compatible with the new SP version of netweaver.
