If you want to be able to upgrade to a Plesk version other than the latest stable release, you can upgrade using the interactive console.

Note: You can upgrade to Plesk Obsidian from Plesk Onyx 17.0 and later. See if your OS is supported. If you use Plesk 12.5 or earlier, upgrade to Plesk Onyx first.

To begin, connect to the server via SSH and run the following commands:

  1. wget https://autoinstall.plesk.com/plesk-installer
  2. chmod +x plesk-installer
  3. ./plesk-installer

This will launch the console in the shell.

If you want to change the directory to which the installer will download files (./parallels by default), run the installer with the --target <path to the desired directory> option:

./plesk-installer --target /tmp/plesk_download

By default, they are downloaded from Plesk servers. However, you may want to install from a different server (for example, if you have set up a local mirror), or from the local disk (if you have downloaded the installation files beforehand). To install from a different source, run the installer with the --source <URL or local path> option:

./plesk-installer --source http://local.example.com/plesk_download
./plesk-installer --source /tmp/plesk_download

If you are upgrading Plesk on a server behind an HTTP proxy, you can configure the proxy server address by adding the --proxy-host <IP address or hostname> and --proxy-port <port> options. If authentication is required, you can set the username and password via the --proxy-user <username> and --proxy-password <password> options:

./plesk-installer --proxy-host http://proxy.example.com --proxy-port 8080 --proxy-user john_doe --proxy-password MySecurePass#123

If you prefer to use a graphical interface during the upgrade, see the Upgrading Plesk for Linux Using Installer GUI topic.
