Upgrade from CRM 8.9 to CRM 9.1
We are currently upgrading our CRM 8.9 on PTools 8.48 to CRM 9.1 with PTools 8.52. We have done the initial upgrade pass and are attempting to do the move to production pass. However our copy of production is 8.9 production on PTools 8.48 and our upgraded 9.1 production is on PTools 8.52. Does that mean for every "move to production" interation we do we have to first do a Tools upgrade?
