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.

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:

@Rainer Kraft

@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.
Hi @Rainer Kraft,
It's hard to provide you with exact steps without taking a look at the issue.
As the license you own was purchased from our partner, you can buy a support subscription and contact Plesk Support Team directly.
Check this article for details: https://support.plesk.com/hc/en-us/articles/213953025-How-to-get-support-directly-from-Plesk-
First 30 days are free of charge.
> Note: Make sure that port 8447 is opened in firewall. If it is closed and cannot be opened, use the command-line instructions.
Can you please elaborate if the mentioned port 8447 is for outgoing (from Plesk to Internet) or incoming (from Internet to Plesk) connections? Or even both directions?
@Claudio incomming
Plesk hung on an update from 18.0.20-->18.0.21. Appears update was incomplete.
Server working fine, but no longer able to access Plesk control panel.
Error log indicates plesksrvstartuphandler.exe failed with error code 255, failed opening required "Loader.php."
When I examine the relevant folder (Plesk\admin\plib), it looks like the files in that folder are incomplete. The files there all show a date modified that matches the time of the upgrade, but the files are all alphabetically "A" through "E" and stop abruptly at "E". It appears any files "F" through "Z" are missing (including the indicated "Loader.php."
It seems the upgrade was interrupted and now I have a problem.
Attempts to reinstall the upgrade through command line seem successfull "you already have the latest version of the product and selected components installed, installation will not continue."
But not able to launch Plesk control panel :(
@Scott Saccenti,
it's hard to propose a solution on the fly, as such issues require direct investigation on the server.
Thus, I'd recommend contacting our Technical Support Team for assistance.
