Upgrading Sage 100 customer from 3.60 to Sage 100 2017.02 ""a broad jump . Test conversion worked. They have ""we've always done it this way"" procedures that include various external systems and calculations. We requested they review all the 2017 modules to be sure all their business processes are covered, but they keep saying ""managers who created the rules have left the company, and we don't have time to test"" (recipe for problems). Does anyone have sample module ""sign off"" sheets that I can ask their managers to sign saying they have reviewed and tested their processes on Sage100 2017modules BEFORE we do the final conversion and GO LIVE?
