I’m looking to see if anyone knows of a tool that can be used in ruby  
to autogenerate a rails migration  
from an existing database that comes from a non ruby project. I know  
I can do this with rake db:backup with a rails project, but does  
anyone know if its possible outside of this realm. I looking to build  
a project to migrate a database from one platform to another. Say  
Oracle to MsSQL server. Migrations would help immensely with this  
concept, but can these be generated and not have to be built?
