I guess that depends on what you mean by "easy". Vector Linux does not support in-place upgrades like the big distros do. Of course, very often those in-place upgrades don't work out so well. Vector Linux does force you to do what I recommend in any casse -- you have to reinstall from scratch. Of course, if you have your data (your /home directory) in a separate partition you don't lose any data or settings which does make things somewhat easier.
VL 5.8 is six weeks short of two years old. That's an eternity in Linux time. It really is time to upgrade.
