Increasing horsepower on license

I tried posting here a few days ago but here it goes again.

Before mar 24 a chief osv came with a dde if asked for with the corresponding hp. Now a chief osv license has completely different seatime requirement and most likely different test modules? Anyway my question is does the dde need to be upgraded to raise the hp or can the hp on the chief alone be raised? Also, can previous seatime be used for raising the hp which previously only time with no regards to hp was used for dde?
