# Uninstalling the Discovery Framework

To uninstall the Discovery Framework, remove the packages and directories that you installed.

If your previous deployment was installed in an existing application server, follow the appropriate steps to stop and uninstall the earlier DF application from the application server before installing this version. For important details on Discovery Framework migration, see the topic "Upgrading from a previous version of the Discovery Framework," located in the Discovery Framework Migration Guide.

Note: You cannot have multiple versions of the Discovery Framework installed on the same machine simultaneously.
