The statement that switch a whole infra from one tool to another is 
"cheap" and predictable sounds extremely naive to me.

Migrating the DVCS content is usually easy. The hard part is then to 
find all the script, tools, doc that rely on the previous tools to 
upgrade them to the new one, sometimes trying to find feature parity. 
This is rarely cheap and never "predictable"
