SAP Netweaver 7.01 to 7.3 Upgrade (Enterprise Portal)

Hi,

I'm just trying to upgrade to Netweaver 730 from 701 (Enterprise Portal).

At the start of the upgrade program "startup" from the Upgrade Master DVD I get the following error:

as-sap-t43:tp3adm 47> ./STARTUP

• Checking if C++ runtime is installed ...

• Running MIDBOOT to unpack and startup...

• Determined SAP system ID as 'TP3'

• Starting upgrade to SAP systems based on SAP Netweaver 7.30

• Using upgrade directory /usr/sap/TP3/upg

• Locating SAPCAR

ERROR: Data unit with attributes 'type=SAPCAR;osname=LINUX_PPC64' not found.

Unfortunately I could find nothing about this error in the marketpplace or in the SDN.

Can someone help me???

Sincerely

Norbert
