Solution:
Please use the following workaround.
1. Bounce the Database completely, ensure that all RAC nodes are down.
2. Update ADOP Repository with the below SQLs :
Take a backup of table.
  1) update ad_adop_sessions set cutover_status='3' where adop_session_id=<session id> and node_name=<host name>;
  2) update ad_adop_sessions set abort_status='X' where adop_session_id=<session id>;
3. After commit, restart Cutover using the same command.
