# Update of existing Installations

In case you already have an existing installation of BDeploy, you can easily update this installation. An update can be performed in two different ways: through the command line (even remotely) or through the Web UI.

For more information about the Web UI, please see BDeploy Update.

To remotely update an existing server, use a command similar to the following:

bdeploy login --add=<server-name> --remote=https://<hostname>:<port>/api
bdeploy remote-master --update=<path/to/update.zip> --useLogin=<server-name>

Updating a local server through the command line is done in the same way.

Note

Existing nodes don't need a separate update. They need to be online when applying the update to the master. The update is applied to all online nodes as well when applying it to the master.
