Hello,
We are upgrading SAP R/3 to ECC 6.0. We have SAP HR, that also needs to be upgraded. Based on this, I have 4 queries, seen below.
1- What are the Pre-reqs and protection of data related activities prior to doing the above upgrade?
2- What are the key tables (in SAP R/3 and SAP HR) to be protected prior to "OR" during a upgrade?
3- What are the key tables (in SAP BW) to be protected prior to "OR" during a upgrade?
4- What is the length of a typical upgrade? (Is there a tool to analyze the expected time duration?)
Thanks for help in advance
