I’m developing a first rails application whith a legacy oracle  
database. I only have access to the datbase at work, but I would still  
like to work from home too.

I need to maintain 2 different “migration environments” in the same  
migration files.

1. At work, I don’t use the up or down methods in my migrations  
classes.
2. At home I would like to “build a copy” of the oracle database" with  
migrations and mySQL.

How can I accomplish this?  
Thanks in advance for suggestions and help.
