The closest thing that we came up with in this regard is a 
pgrouting_legacy.sql that is here:
https://github.com/pgRouting/pgrouting/blob/master/src/common/sql/pgrouting_legacy.sql

Do not expect this file to work? but you can use it as an example of how 
you some of the old commands could be mapped to the new ones. This file 
has not been tested or validated in any way, but I put it together with 
the thought that it might help someone with understanding how to migrate 
1.x to 2.0.

Hope it helps,
