Upgrade ReadyNas 102 to newer model

[Officespaced]

I have a ReadyNas 102 that has served me well over the past couple of years.  In addition, to file storage and backup, I utilize the optional Plex software.  This last piece is what I'm looking to improve performance with, by purchasing more current hardware.  Are there particular ReadyNas products where I can drop in my existing two drives (RAID) and not lose my files?

Best to uninstall all apps before attempting a migration if moving to an x86 box. Can move to any OS6 unit.
