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

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.

Follow these steps to begin:

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

This will launch the installer in the graphical interface mode. To access it, open your browser and browse the following address:

https://<server hostname or IP address>:8447

If you prefer to use a command line console during the upgrade, see the Upgrading Plesk for Linux Using Installer Console topic.
