Migration of NAS200 - move to Jac4 Hello all, I wanted to see if anyone might know or have tried... I have two disks in RAID1 on a NAS200 with stock firmware V3.4R79 I am considering to upgrade to Jac4, but I am curious if I might loose access to my data. I realize a backup is the cautious thing to do... but I really don't have the space to back it up elsewhere. If I pull one drive and try the Jac4 firmware and something goes awry, can I flash back to the original firmware and use my other drive to "return to normal"? Thanks all! -Cheers, Peter.
