Hi all, many years ago, I have installed the DSM Version 4.2-3211 on a HP N40L with AMD Turion. I´m running it on a USB stick with two HDD with Raid 1. It´s still running fine, however I would like to update to a newer version. What would be the best way to do this? Can I install the DSM on a new stick; simply replace the sticks and the new version will recognice the two hard drives with the volume? Or should I upgrade 4.2-3211? Thank you for any feedback.
