well i think it is simple. just load your character and open the pose exporter that you will find under the scripts folder inside daz studio.
 a window will pop up. uncheck everything that has relation with rotation translation scale etc. and check only the option that says export morphs and chose the directory that u want.

in that directory you'll find your pose. just make a png image of 99x99 size dimension and give it the same name as the pose. create a folder in the runtime/librarie/pose/ destination and paste the two file into it. now in daz look in the pose section and open your folder that u created. you'll find the pose. if you load v4 and double click the pose. it will turn into your character.

note : if the person that will have your character doesn't hava the morphs that u used to create yr character (for example v4 morph ++) the pose won't work because there's no morphs to load.

that's just one way to do it.
