That's cool :-) I didn't know about that.

Nope. The migration scripts are pretty dumb. They do not "know" if they 
have already been run or not. You really have to drop the database, 
re-install your backup of the original and run again. Repeat until it works.

Agreed. But I very much doubt that will happen in the short term.

Hint: try converting the migration scripts to run from the php cli. It 
is much more manageable - although probably only worth it if you do a 
lot of migrations.
