Dawn, Sage did ""give"" Abra to our 3.74 customers who owned the payroll module. The reason I say ""give"" is that the software was free as long as they started paying maintenance on it. If Sage doesn't voluntarily give them SQL payroll, I would certainly ask them for it.
A data conversion utility...not happening. I'd be surprised if there is BR integration.
Also, from experience, there is a damned steep learning curve for customers moving from MAS payroll to Abra SQL payroll (which is the Accpac payroll). I'm not saying that you can't get there (we have helped customers get there) but plan accordingly.
