Hi,
We need to upgrade our ECC6.0 to either EhP5 or EhP6. It's required for an add-on vistex. I have few questions:
1. Our ECC production is 5TB. Why do we need a full system copy on sandbox. Can we use TDMS to bring configuration and master data and do our first test upgrade? How can we make sure our timelines for production unless we have a full system copy? I believe we'll be refreshing our QA with full copy of production. If we do not get approval to go for full copy of prod on QA what are the consequences?
2. Since EhP5 is old shouldn't we go for EhP6?
Regards,
SJ
