Experts :
As of now we have one server on which one SQL Instance is there which needs to be converted to alwayson sync replication between 2 Alwayson instances in a DC(By following the required steps).
On the existing SQL Instance Is there a way to calculate the change of data(Databasewise in MB/GB) for judging the amount of data flow which will happen between the always on setup which will be coming up.
