switch from catch Kathmandu to parallax

dear all, currently I use catch Kathmandu, but I would like to switch to Parallax frame. When I checked the preview I recognized you use now pages instead of posts for the featured content on the homepage and featured slider in the head. Is there any way I can migrate from Kathmandu to Parallax without restructure content, want say to use posts instead of pages? thx and regards seeker
