# Uninstall on Linux

This section will help you perform a complete uninstallation of WebSpellChecker Server on a Linux-based environment.

1\. [Stop AppServer](https://docs.wproofreader.com/v6.12.0/deployment/installation/linux/pages/IA2KNQLXDh85TwDivL4y#mainappservercommands-stopappserverwindowslinux2.stopappserver) if it is running.

2\. Uninstall the existing copy of the application as described below.

If you have any custom settings and/or dictionaries that you plan to reuse, you need to back up them before uninstalling, migrating, and upgrading.

For example:

* If you have already changed any values of the [AppServer parameters](/v6.12.0/deployment/configuration/application-server/appserver-parameters.md) in AppServerX.xml configuration file, you may need to transfer these settings to a new server. Otherwise, these parameters values can become incompatible.
* Back up the **CustomDictionaries** folder (\<WebSpellChecker\_Installation\_Path>/AppServer/CustomDictionaries) with global custom dictionaries and its CustDictConfig.xml configuration file.
* Back up the **UserDictionaries** folder (\<WebSpellChecker\_Installation\_Path>/AppServer/UserDictionaries) with all personal user dictionaries created by end users.
* Back up the **StyleGuide** folder (\<WebSpellChecker\_Installation\_Path>/AppServer/StyleGuide/client) with global style guide rules.

a. Deactivate a license. Refer to the [License Deactivation on Linux](/v6.12.0/deployment/licensing/license-deactivation-on-linux.md) guide for details.

Please note that if you want to install your application package on a different server, you need to deactivate your license first.

b. Run the **rm -rf** command to remove the application files:

```
sudo rm -rf <WebSpellChecker_Installation_Path>/WebSpellChecker
```

```
sudo rm -rf /var/lib/WebSpellChecker
```
