Uninstalling your Self-Hosted Standard Edition

Uninstall the Standard Edition from your cluster.

Before you uninstall, take a backup of your resources if required. For more information, see Backing up and restoring.

The stanctl cluster delete command uninstalls the Standard Edition and removes all the data. If you want to keep the data, use the --keep-data flag.

To uninstall and remove your data, run the following command. In a multi-node cluster, run this command on node0 (instana-0).
```
stanctl cluster delete
```
At the prompt, confirm the deletion.

To uninstall but keep your data, run the following command:

```

The uninstallation does not delete the instana.yaml configuration file that is in the $HOME/.stanctl/ directory. If you reinstall Instana on the same host, the installation uses the configuration values from the existing $HOME/.stanctl/instana.yaml file. If you want to use the host for a fresh installation, remove the instana.yaml file before you reinstall.

In a multi-node cluster, the instana.yaml file is on node0 (instana-0). If you want to do a fresh installation, you must remove the instana.yaml file on node0 (instana-0) and then reinstall.

Use the following command to remove the instana.yaml file:

rm $HOME/.stanctl/instana.yaml
