That doesn't sound right - rake db:migrate runs migrations that have not been run by comparing the contents of the schema_migrations table with the list of available migrations: it doesn't just assume that everything upto the largest entry has been run (unless possibly you are using the legacy pre rails 2 migration numbering scheme - no idea if that is still possible) The only exception to this is that if you run db:schema:load then it assumes all migrations upto the version named in schema.rb have run.
