I was told to not touch the application, but what I can gather so far from "winver" and Control Panel is.

It runs on Server 2008 SP2
Quickbooks programs are 

QB Enterprise Server 9.0
QB Enterprise Solutions: Retail Edition 9.0
QB Point of Sale 9.0

QB File Doctor

I would like to download QBES: Retail Edition 9.0 trial version, create sample data and then upgrade to latest version as a test to then be able to bring this tested solution forward.

Any thoughts?
