Question

How to upgrade Plesk to the next release?

Answer

Plesk can be upgraded either via the Plesk interface or a command-line interface directly on a Plesk server.

During the upgrade process:

  • Plesk will be unavailable
  • Websites will stay online

Notes: To find out if your operating system is supported by the next Plesk release, visit the Plesk Lifecycle Policy page.

Note: Make sure that port 8447 is opened in firewall. If it is closed and cannot be opened, use the command-line instructions.

  1. In Plesk, go to Tools & Settings and click Updates and Upgrades.

  3. On the Install or Upgrade Product page, select a Plesk version from the drop-down list and click Continue to begin the upgrade procedure.

    Note: If your operating system supports the next Plesk release, but it is not in the list, check what release tier you are currently on at Plesk > Tools & Settings > Update and Upgrade Settings.

    • On Windows Server, start a command prompt as an Administrator and run the command:

      C:\> "%plesk_bin%"\ai.exe --console

    @Alessandro Marengo

    Hello!
    Could you specify which version is currently installed?

    Generally, please try to start Plesk Installer with the parameter --all-versions, for example:

    "%plesk_bin%"\ai.exe --console --all-versions

    Thanks Ivan for your reply.

    What if, instead of using command line, I'd like to use Plesk Updates option?

    @Alessandro, this option is available only in CLI version of Plesk installer. If you cannot see the desired version for the upgrade, it may mean that your OS does not meet all requirements.

    Running /usr/local/psa/admin/bin/autoinstaller says that it should only be ran on clean install servers and that I should backup my data, so I am not sure I should proceed:

    ------ IMPORTANT ------

    * New installation of product(s) should be performed on clean servers only.

    * Before upgrading Plesk, be sure to back up your data.

    * By using this Wizard you agree to the terms and conditions described at
    http://www.plesk.com/legal/terms/ and those of the Plesk End User
    License Agreement.

    Available actions:
    (F) Go forward
    (Q) Cancel installation

    Hi @adrianTNT!

    In case you are updating Plesk, the warning about clean server may be ignored, this is for new installations only.

    As for backup, it is a general recommendation in case the update will fail (usually the process goes fine). You may make a server snapshot or backup Plesk domains.
