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. 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 want to upgrade to the latest preview of the upcoming release, run the following command instead:

./plesk-installer --web-interface --tier testing

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