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.

Upgrading Plesk via the Plesk interface

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

In Plesk, go to Tools & Settings and click Updates and Upgrades.
On the Updates and Upgrades page, click Install or Upgrade Product.
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.

For detailed instructions, see:
- Plesk Documentation: Upgrading Plesk Using Administrator GUI

Upgrading Plesk via a command-line interface

Connect to a Plesk server via SSH/RDP.
Start Plesk Installer:
- On Linux, run the command:
  
  # /usr/local/psa/admin/bin/autoinstaller
- On Windows Server, start a command prompt as an Administrator and run the command:
  
  C:\> "%plesk_bin%"\ai.exe --console
Follow the on-screen instructions. For details, see:
- Plesk Documentation: Upgrading Plesk for Linux Using Installer Console
- Plesk Documentation: Upgrading Plesk for Windows Using Installer Console
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. Alternatively, quit Plesk Installer and start it once again with the key "--all-versions".

@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:

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.
