We are upgrading our BI (Dual stack system From NW 7.0 to EHP1 NW 7.3. I have gone through some docs and found we have to split the stack before upgrading. The system have SEM-BW and FINBASIS of release 603..
My questions are
1. is is it mandatory to split the stack or is their any way we can perform it with out splitting...
2. Can we perform direct upgrade to 7.31 or we have to apply any EHP in the system
3. We also have cluster in production environment, what will be the ideal approach to perform upgrade in production environment.
