Regardless of which numbering style you choose to use, prefix your migration
files with the migration number followed by an underscore and a descriptive
name for the migration. For example:
-* **001_add_blog.php** (sequential numbering)

-
-$this->migration->current()
-============================
-
-The current migration is whatever is set for **$config['migration_version']** in
-**application/config/migration.php**.
-
-$this->migration->error_string()
-=================================
-
-This returns a string of errors while performing a migration.
-
-$this->migration->find_migrations()
-====================================
-
-An array of migration filenames are returned that are found in the **migration_path**
-property.
-
-$this->migration->latest()
-===========================
-
-This works much the same way as current() but instead of looking for
-the **$config['migration_version']** the Migration class will use the very
-newest migration found in the filesystem.
-
-$this->migration->version()
-============================
-
-Version can be used to roll back changes or step forwards programmatically to
-specific versions. It works just like current but ignores **$config['migration_version']**.::
-
- $this->load->library('migration');
-
- $this->migration->version(5);
