Hi,
We are planning to do Technical upgrade our SAP R/3 4.6C to ECC6 soon.
Below are the list of question I would like to ask:-
Our source:-
SAP R/3 4.6C
HP-UX IA-64bit
Oracle 10.2.0.4 previously upgrade from 9i
Target system:-
SAP ECC6
HP-UX IA64bit
Oracle 11g
Question 1= Will it be a problem to upgrade the Oracle 10G to Oracle 11G after the SAP upgrade? Because the Oracle 10G version is an upgrade from 9i previously. I find out the tablespace is still old local managed tablespace.
Question2= SAP always recommend to have 3 system landscape. But our current system only have 2 system landscape. DEV & PRD only. Is it a must for future ECC6 system to have 3 system landscape?
Question3= Can we do a direct upgrade into the current DEV & PROD server? We want to save cost and used back the current servers.
What is the real problem if I do that because SAP recommend to system copy to a new server and upgrade using a new server? If I direct upgrade the DEV after 1 trial run, I can see that we will have to freeze the development for longer time for the ABAP team to make all the adjustment.
Thanks.
Best Regards,
CK chai
