Hi, for VaM you will need a .DSF morph file from DAZ. I suppose, you have a single (or head/body) morph file and not a character that is created by using multiple morphs. In both cases, if you don't have a .DSF file, or a created character, export it as OBJ and re import it in DAZ with the build in morph creator. Please ask if you have detailed questions on this.
Once you have a proper Genesis 2 .DSF file in DAZ, just copy it over to VaM in the following folder: ...\yourVAMfolder\Custom\Atom\Person\Morphs\female(or male). You have to restart VaM to see the new morph.
For better sorting, you can open the .DSF file with a text editor and change the "region" : "xxx" to a location you want it to appear. If you can't open it, just unpack it with a ZIP tool. VaM creates automaticaly two additional files for your morph with the first run, so you better edit the .DSF before that first run, or simply delete the two additional files (.vmb and .vmi).
BUT: Don't be too disappointed, the morph will never look the same like in DAZ for some reasons. VaM is doing for instance a lot of smoothing and other stuff, that will iron out many fine details, and so on. Best way is to use the DAZ morph and then edit the persons look in VaM until you are somewhat satisfied. You could try to lower the VaM smoothing in the settings, but most of the time this makes things worse.
