QUESTION POSED ON: 14 May 2007
We need to migrate from a MF/DB2 v8.2 to a HP-UX/Oracle DB. We are running with mySAP ERP 2004, ECC 5.0 with NetWeaver 2004, ABAP stack only, and 5 lower life cycle systems in the landscape. Can we move to mySAP ERP 2005 ECC 6.0 with NetWeaver 2004S? Please explain the timeframe as well as the steps involved.

EXPERT RESPONSE
I do not see any reason why you would not be able to move to ECC 6.0. The first step would be to migrate the SAP environment to HP-Unix / Oracle. Next, the upgrade to ECC 6.0 can be started.

The migration to the new platform will probably take you at least several weeks and up to a couple of months, especially if new hardware needs to be ordered, installed, and configured. Adapting interfaces and output management to the new platform should also not be underestimated. In addition, in-house developed ABAP reports which use database dependent functionality need to be adapted to the new RDBMS.

The time needed for the upgrade to ECC depends on the number of SAP modules in use and the number of modifications to the SAP standard and the in-house developments.
