QUESTION POSED ON: 22 January 2009
During a recent change freeze, and after a full offline backup, I am restoring a backup of my current production FICO system onto another server to act as a system reference. I'll do this before making major changes to my live production system.
How do I prove to my colleagues that the restored (reference) copy of the FICO system is a true and accurate copy of actual production before I make the changes to my production system? In other words, how do I prove that the backup is good, and the restored system and business data in both systems is identical?
I have written an ABAP tool to reconcile between my production and reference systems, as well as between all companies and FICO ledgers over an eight-year period. The current signoff is that if they both come out the same after reconciliation then this is good proof that they are identical.
