Roamio Upgrade while Preserving Recordings - Possible?

Apologies if this info is someplace else, but I'm having a hard time finding a definitive answer:



Is there currently (Spring 2014) any way to upgrade a Roamio drive while preserving recordings?



(I have Time Warner Cable, so I can't copy off my recordings any other way.)



Is there any newer version of JMFS than 1.4 - http://ift.tt/1fK8Uga ?



Thanks
