Hi Guys, I recently built an XPEnology NAS from an old PC four spare 1TB HDD’s. It’s working fine, has been for a few weeks now and I’m very happy with it. However, I noticed that the version of the DSM was DSM 5.2-5644 and it is suggesting that I can upgrade to 6.0-8754, is it safe to just do this or is there a special procedure that I should follow? TIA Roly
