You can get genesis into PP2014 at high resolution. That is not really the problem. The real problem is afterwards: Each time when new morphs for it are released you have to create a new genesis figure with the new morphs added. This makes the figure very large. The other problem is that you will need the morphbrush to correct any pokethrough after posing to compensate for the different rigging of genesis - this works fine most of the time, but can be tricky when limbs are too close to the body.

Then there is the problem of all the poses, expressions, props, clothing which are all delivered in DUF format - so you will have to convert each of them to poser format. Add to that, that you have to make sure that all the morphs are present in the clothing before you convert to Poser format. This is a very timeconsuming process if you have to do a lot of them

And of course you have to adjust all material settings if there is no poser equivalent in the product

With the DSON importer most of this is taken care of. But it is at the expense of serious performance problems

I occasionally use genesis: I load a genesis figure in a poser enabled PP2012, add the clothing, hair and the morphs and materials. Then I save the entire set to the library. After that I can use the figure in a non-DSON enabled PP2014.
Of course if you want to change the clothing or add a morph you have to do the whole thing again
