We are in the process of upgrading our BI 7.0 system to BW 7.3. Our plan is to take a copy of the existing BI 7.0 system to to new system and perform upgrade in the new system, so as not to affect the ongoing activities.
First, dev BI is copied to new system and new system is upgraded to 7.3 and so on to PRD BI system. In this approach we are concerned about the production system down time of ECC.
Can anyone share your experience in upgrade projects from BI 7.0 to BW 7.3.
I went across the documents and threads posted in SCN but could not find any.
