Unfortunately solid works is not forward compatible, only backwards compatibility. For instance in solid works I may open a model from older versions, but not from later years' versions.
It may be good enough to transport them as .x_t but you loose the model tree.

You can upload the files needed onto GrabCAD workbench and then proceed to download them in whichever format you were in need of.

It works as a third party conversion site, ish.
