Upgrade/Year End Question. - Client is on v4.40 PU9 - Needs to upgrade to v2014 for year end Payroll and A/P updates. Multiple ""hooks"" in several modules between SAGE 100 Standard and several custom Access databases. Programmer states he will not be able to test all his ""hooks"" in v2014 by year end. Can I migrate the v4.40 data and convert to v2014 after the last payroll and vendor checks are written in version 4.40. Then perform all my year end tasks (W2s, 1099s etc.) in v2014, using Aatrix to process tax forms. electronic filing, etc. Then sometime in January 2015, when the programmer is ready, I would migrate and convert v4.40 data to v2014 again. What am I NOT thinking about were this would NOT work?
