A method for transferring an instant messaging and presence (IMP) session from a source device ( 101 ) to a target device ( 103 ) includes the steps of registering ( 130 ) the target device with an IMP server ( 105 ), sending ( 150, 152 ) historical IMP session information from the source device to the target device, and subscribing ( 170 ) the target device to the IMP server. The target device ( 103 ) initiates the transfer of historical IMP session information (thus, we refer to it as a "grab" or "grab transfer"), and the target device ( 103 ) may optionally instruct the source device ( 101 ) to de-register ( 160 ) from the IMP server ( 105 ). Related methods for the target device and the source device are disclosed as well as an electronic device operable to be either a source device or a target device.
