How to rename custom module

[Tje123]

I have developed a custom module and install it from back office.lately i got a requirement to change the module name.

I tried these steps.

1. Rename my module folder name (my_shipping -> shipping_module )
2. Rename module file under modules folder (my_shipping.php -> shipping_module)
3. Rename class name and name 

class Shipping_module extends CarrierModule
{
    protected $config_form = false;

    public function __construct()
    {
        $this->name = 'shipping_module';
        $this->tab = 'shipping_logistics';
        $this->version = '1.0.0';
        $this->author = 'DDD';
        $this->need_instance = 0;

}

}

Then i have refresh my back office module selection and i saw it under `installed modules` tab.(but i've started these steps when uninstall it).then i tried to uninstall it .then it show me

How to rename my existing custom module?

Hi Tje123,

First of all, you need to uninstall your old module(my_shipping). Rename it. And install the new module (shipping_module)

If you rename the module when is installed,  then it will not work.
