lan_baba Posted March 30, 2014 Share #1 Posted March 30, 2014 Currently I have the 4.1.2668 running on 54L. Is there a way for me to upgrade to the latest 5.0.xxxx without loosing my data? I have 2 RAID 1 running on the system and an additional 250G(the stock HDD) hooked up with the optical bay. Unfortunately, I do not have enough external HDD space to back up the data. A Step by step instruction will be really appreciated, I've read the board for the whole night and haven't figured out a way yet. big big thanks.
