BioWare is currently offering rewards for players who have active accounts on SWTOR and have taken part in the server transfer program (or just happen to be on one of the destination servers). This means that both players who have already transferred and players that transfer now will be eligible. It seems that the goal here is to get more players transferred and off of the quickly-emptying origin servers.
All of the details can found here. The rewards are pictured above, a little Gannifari companion and 25 Black Hole Commendations. Players eligible for these rewards will receive both, and each character transferred will receive them.

The response to the Free Character Transfer Service so far has been fantastic. Hundreds of thousands of players have already taken advantage of this free service to move their characters to new servers where it’s easier to find groups and play with friends. This initial service is still available and allows qualifying characters to be transferred at no charge from selected origin servers to selected destination servers.
In appreciation for the community’s support of the Free Character Transfer service, we are giving all characters on qualifying servers (including all destination servers) an in-game pet, the Gannifari, and 25 Black Hole Commendations to help purchase high level gear. Visit www.swtor.com/transfer for a list of qualifying servers.
If you haven’t moved your characters yet, it’s not too late. Transfer now to receive these in-game rewards!
