Ok, well if he wants to transer it theres not much he can do. You can try to link it to his website by editing one of the files in PHPNuke but then i don't know if you will be able to make it fit the page for phpnuke like other sites. If he has the files for the forums then just transer them using FlashFXP or some other file to transer those and replace all of the other PHPNuke forum files with those.
