The correct way to upgrade a SAP
We are trying to upgrade an old system with :
to a new (test) system with
SAP ECC 6.0
The correct way seems to be performing an homogeneous system copy from old to new.
Now, the question is .....
Is it possible to perform an homogeneous system copy with different versions of Oracle ?
Is it necessary the Oracle versions are the same ?
Or .... There it exist a procedure to perform an homogeneous system copy to a higher version ?.
Performing directly the HSC from 9.2 to 10.2.will save us a lot of time.
