Sure - it's a special situation (or at least, it is special to that company - a fairly large financial institution, IIRC).
But my point is that 10 year old software is and will be used in production in a lot of places. I see this with Sybase, where old(er) versions are being EOL'd (i.e. bugs found won't be fixed, etc), but that doesn't really stop a lot of places from still running various versions of 11.0.x (ca. 1995), because the system works, they don't need any of the new features introduced in later versions, and upgrading can be a huge pain for 24x7 shops.
