Can SD+ manage this??

I ask as we have 3 installations and would like to manage from one console/application server, but keep databases seperate as they now are quite different?

Can this be done and if so how? 

I know I will need licences to do so, but can work with that, but what else do I need?

Am running MSSQL, SD+ 7008, moving to 750? very soon, once testing is sorted on TEST environment
