RenumberMigrations
==================

Fix migrations that have duplicate version numbers.

Example
=======

oh the horror:
db/migrate/001_create_users.rb
db/migrate/002_create_planes.rb        <-- AHHHH!
db/migrate/002_create_helicopters.rb
db/migrate/003_create_army_guys.rb
db/migrate/004_create_cheese_wheels.rb


First, move the duplicate version numbers that you don't want to renumber to a safe place:
(only applies if you didn't catch the duplicate migration before it got inserted)
$ mv db/migrate/002_create_planes.rb ./

Second, run the renumbering rake task:
$ rake db:migrate:renumber VERSION=2 TO=3
> ==  Migration Renumbered: 002_create_helicopters to 003_create_helicopters
> ==  Migration Renumbered: 003_create_army_guys to 004_create_army_guys
> ==  Migration Renumbered: 004_create_helicopters to 005_create_cheese_wheels

Now, if you had to move any migrations earlier you should move them back:
$ mv ./002_create_planes.rb db/migrate/
