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
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.
Note: If Plesk Obsidian is not available for upgrade, visit this KB article.
-
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:

Start Plesk Installer:

What can I do if there's no update available?
@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.
Hi, I'm running Plesk Onyx on CentOS 7. "Install and Upgrade Product" is grayed out. In the "Update and Upgrade Settings", I have General Release selected. Is that the issue potentially? Thanks. - Ignore this got it running, how can I tell if the upgrade is stuck. Been running for 2 hours now still on 45/17something.
Hello @Michael,
Please check the last records in /var/log/plesk/install/autoinstaller3.log. If the file is not updated then the upgrade is stuck.
In this case please kill the existing installer process using the article:
https://support.plesk.com/hc/en-us/articles/213917525
After that, run Plesk upgrade using the command line:
# plesk installer
The solution regarding grayed out Install or Upgrade Product option is described below:

@Lev lurev
That's not possible, 'cause I got Plesk from my Provider and it is not possible to get any more help, than this forum. Here are some lines from the log:

If I search for postfix-2, there is no result on the server
Warnung: Keine Übereinstimmung gefunden für: postfix-2.10.1-7.el7.x86_64
Perhaps it points someone in the right direction. I stopped the update for now.
