I am thinking about our company BW system upgrade plan and want to collect correct information.
After searching SDN for this kind of upgrade process, I listed what I should do for our upgrade plan, please help me to see if my steps is workable and advice me if there is another possible to do the upgrade.
As-Is --> Running SAP BW3.5 Netweaver 2004 with database Oracle 22.214.171.124, windows 2003 32bit environment.
To_Be --> Running SAP BW7.3 Netweaver 7.3 with database Oracle 126.96.36.199, windows 2008 64bit environment
Step 1 --> Install new windows 2003 operation system with 64bit
Step 2 --> Homogeneous system copy for our BW 3.5 from windows 2003 32bit to windows 2003 64bit.
Step 3 --> Upgrade database from 188.8.131.52 to 10.2.0.4
Step 4 --> Upgrade BW3.5 to BW 7.3
Step 5 --> Migrate BW 7.3 from windows 2003 64bit to windows 2008 64bit.
Am my steps right? Any wrong steps need to adjust? Or other suggestions for my upgrade purpose?
