HI,
Where it was terminated, on a Local or on any standalone controller ? if it was on the stand alone controller please ensure you have same configuration on the new controller other wise you have to purge the AP and re provision it.
or if it is on a local controller please ensure that the local is in sync with the Master.
generally what happens is, if an AP is provisioned it will remember it's AP-Group name and it will try to pull that AP-group from the terminated controller in case if that controller is not having that AP-grpup configured , controller will show that AP with "D" flag.
Hope got some clarity, please feel free for any further help on this.
