Might be too late but I would try the following:
1) Reboot SS
2) Make sure all elements (SS, CS, MGC, MC32) are either all reg or all not reg to the security domain
3) Try to transfer the node
4) Log into EM and see if the node is still there if not import it from SS or CS
5) Save the node
6) Make sure all elements (SS, CS, MGC, MC32) are either all reg or all not reg to the security domain.
7) Try to transfer the node.
8) Try to reload the database and the try to transfer the node
9) Reload the CS software and database
