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.
