SAP NW Upgrade form 7.01 to 7.4
We are planning to go for an Upgrade with our Portal which is currently on 7.01 SP9 .The Usage types are AS, DI ,EPC and EP and JVM Version is 4.1.
Our Oracle is Upgraded to 11 and OS is AIX 6.
As per my understanding the OS and DB are compatible for the Upgrade ,the JVM needs to be upgraded to 6.1.
I have few queries regarding the Upgrade
- How to generate the component stack (stack.xml) file without the solman and mopz .Is stack.xml file mandatory for the Upgrade .
- If we download all the components manually without the help of stack.xml file and put this in trans/EPS folder and run SUM will this work.
- how to upgrade the ESS business package, and configure it.
- Any take care points before and after the Upgrade.
Any docs related to the upgrade and issues faced while upgrade would be helpful.
