It appears that the only thing that worked was in addition to removing the port-security settings I had to "no switchport mode access" the interface along with a shut/noshut and add the "switchport mode access" and port-security setting back.
That seem to clear the interface so that it would not err-disable anymore and recognize the new mac-address for the swapped system.
I tried all of the clear port-security commands with no resolution to the problem.
