I've got an old install of 9.1 (FreeNAS-9.1.0-RELEASE-x64) that needs to be upgraded. The box has 16gb of RAM so I think I'm good there. Wondering if it's advisable to go straight to 11 via the iso, or should I do it incrementally with .txz in the GUI to get to 9.3 first and then switch trains? Config is backed up. Appreciate any advice.
