How to reset codeigniter migration version?

[kumanan-c]

I am resetting 'config/migration.php' $config['migration_version'] = 1; and renaming the file name 'migration/001_users.php', but it shows following error.

"This migration could not be found."

thanks in advance

Migrations are part of the CI core now. You should use those instead.
