We are getting further down the path of upgrading our sites from Micros 4.x to 5.x We use PM, LM, FM, Forecasting and Icare. We were told today from Micros to have a successful and issue free upgrade we would need to clear all our totals for everything before the upgrade. That hampers a lot as we use our historical data for a number of things...Forecasting, PM, FM especially. We also started at version .9 and have never had to clear totals before to upgrade. Any comments or thoughts?
