More than a year after launching V7, Vignette still runs V6 on its own website. Note the telltale URLs -- like "0,2097,1-1-2049,00.html" -- that V6 employs for dynamic page assembly. More accurately, vignette.com runs V6 and V7. The latter operates behind the firewall as a proper CMS; the former does content delivery to public site vistiors. Vignette says it maintains V6 on its live site for migration-training purposes and plans to cut over completely later this year. That's reasonable. But Vignette has recommended a similar hybrid approach to several other customers. You see, V6 is a fairly mature content delivery engine, with personalization, caching, and so on. V7 does not deliver content (that's OK) and has almost no notion of content assembly (that's a problem). Vignette's content delivery choice du jour is supposed to be newly-acquired Epicentric Portal but you won't find it on vignette.com. No wonder several major customers with advanced V6 implementations aren't ready to try the new dog food yet either...
