it isnt clear to me how to update an old fez raptor board to the new TinyClr . is there a roadmap for dummies ?
how much of the doco have you read?
If you start here http://docs.ghielectronics.com/hardware/legacy_products/gadgeteer/fez_raptor.html or here http://docs.ghielectronics.com/hardware/legacy_products/gadgeteer/intro.html#with-tinyclr-os you can see that you need to first move to Bootloader V2, and here http://docs.ghielectronics.com/hardware/products/scm/g400s.html you can find more info specific to Raptor/G400.
Process is very similar to previous netmf releases. Bootloader update if needed, firmware update if needed, and PC software update if needed.
