You can run migrations one at a time by passing VERSION env variable (see
http://guides.rubyonrails.org/active_record_migrations.html#running-migrations
)
I too see inconsistency here. I wish all operations supported both STEP and
VERSION.

It seems that rake db:migrate doesn't support STEP, e.g. "rake db:migrate
STEP=5" will do the same thing as "rake db:migrate", ie run all remaining
migrations. whereas rollback and redo do support STEP.
For the sake of consistency as well as supporting migrations one step at a
time, db:migrate
