"It's the natural upgrade path from alpha"
Oh hell no. They made us do that at ABB and it was like time travelling back to 1984 when 4.2BSD and SVr2 were hotness. Plus the Itanic compiler sucked: you really DID have to build a whole environment to generate to generate traces from your actual application and then recompile using them to get decent performance. There is no possible universe where Itanic could be described as an "upgrade".
