While I'm sure it's possible, it will likely be a massive undertaking that you'd want Unify to do. The oldest I've worked on is a V4. V4 to V5 was done via a hard drive swap with the new software pre-loaded, to save downtime. V5 to V6 requires new processors. I'm sure some of the other salty dogs on here can comment on the older versions.
