Transfer PT HD9 licence

I bought a PT 9HD licence quite a number of years ago without any hardware. Seems the seller at the time had more licenses than hardware so sold one, which included a genuine AVID disk with activation code. Obviously such a licence has some value with respect to updating to PTHD11.



I've tried negotiating the tangled web of AVID read me files and FAQ etc and really can't get straight information regarding me now transferring that licence to someone else.



Any help from my learned colleagues? Thanks in advance.
