I've tested the Oracle upgrade on the test SAP system prepared as homogenous system copy of production. Everything works fine.
Now I'm preparing the day plan for Oracle upgrade but for hole SAP system landscape: PROD, DEV and QUA which are in the transport landscape.
Can you please share your knowladge about the DB upgrade of Development and Quality assurance system to version 126.96.36.199 and production to be on Oracle 10.2.0.4 for one week?
What if we need some development and import some transport requests from dev->qua->prod?
Thank you in advance.
