I'm tempted to upgrade my N3200 to SSH version, but I don't want to loose my files on N3200. I have RAID 5 with 3 500Gb drives, so total capacity is near 1T and backup of all files is a bit a problem. I have only 200Gb free space, so I need 800Gb of free disk space to do the job. I wonder if any of you, who has updated FW to the newest ssh version, tell me what happens to the data files on N3200? Did you have any problems? Did you loose data? Did RAID array start to rebuild after update?
