Import gerbers from Altium to PCB Editor 16.6

Hi.

I work with ORCAD PCB Designer Professional 16.6. I tried to import gerbers from altium (with .GBL, . GBS, .GML, .GTL, .GTO, .GTP, .GTS) but I couldn't.

So, it is possible to import that altium gerber files to this version of PCB Editor?

  If it is possible, how can I do that?

And if it is not possible, it is possible in other version of PCB Editor or do I need some tool independently PCB Editor version?
