Is it possible to use DOORS 9.5 Licences for DOORS NG 6.0.6?

According to this conversation https://jazz.net/forum/questions/98343/installing-doors-ng-401-with-doors-9-licences it was possible to install DOORS NG 4.0.1 with DOORS 9 Licences. Is it still actual for DOORS NG 6.0.6? Is it free of charge? And is there any way to use the same license server for both DOORS NG and DOORS 9 (I mean if this products can use the same pool of floating licenses)?
One answer

The same policy continues. You can use any combination of DOORS 9.x and DOORS Next Generation licenses at the same time up to your total DOORS 9 entitlements. DNG uses Jazz licenses (activation kit loaded into the Jazz Team Server) rather than floating licenses managed by the Rational Common License Server (unless you are using tokens).
