I'm not sure what you mean by this, but I'm interested. Could you explain?
they site some numbers by Gartner (from '99, when 2K scare was on everyone's mind)
"...
Cost of doing a manual migration:The Gartner Group notes that the cost for manual code conversion can range from $6 - $26 per LOC and is accomplished at a rate of 160 LOC per day (Gartner Group study "Forecasting the Worldwide IT Services Industry: 1999,1").
An assumption is that the migration is going between two relatively similar languages (e.g., not trying to go from COBOL to full object-oriented Java). Using Gartner's numbers, a million lines of code costs $6-$26 million to migrate.
Time to do a manual migration: Again, using Gartner's numbers, a legacy system with a million lines of code requires some 28+ man-years of labor to convert. With a team of 10, this takes 3 elapsed years if done well. With larger systems, one has larger teams. Larger teams require more interactions, slowing them down further.
A 10 million line application simply doesn't have any practical manual migration due to time frames.

Never used their services.
But I do think this will continue to be difficult, yet beneficial option, for the migrations from legacy/less secure software.
i.e. analyzing and modifying the huge legacy of existing code base ?
This is a very difficult area of course (both financially and technologically). But the pay off can be very large. Imagine a vmware-like transformation at the source code level.
