Narrative:

At the time of the event; training was in progress with all positions combined to sr (southern radar) during a period of moderate traffic. Aircraft X was an over flight transitioning the bhm sr airspace. When attempting a handoff with aircraft X to (northern radar); the tag for aircraft X was accidentally dropped during the split off of the two radar positions. Aircraft X continued on his flight plan route into the adjacent facilities airspace with no automation or manual handoff being accomplished.I would recommend the positions be split before the workload becomes moderate/heavy and complexity becomes difficult.
