Migrations - very confusing

in my app,

my config migration_version is set to 1 and it's run all my 001_* files. did you try to use version 2 ?

I use this piece of code

PHP Code:

$this->load->library('migration');
        
if ($this->migration->current() === FALSE)
{
    show_error($this->migration->error_string());
    exit;
}
$version = $this->migration->current();
echo 'Migration Done for Migration_id : ' . $version;
