I went through the step and the Upgrade page doesn't show an available update from Onyx to Obsidian and Install and Upgrade button is greyed out. I tried Plesk Installer directly on the server and same problem.
I'm running Windows 2008 standard.
thx
@Glenn,
That's because Plesk Obsidian supports Windows Server 2012 and higher. All software requirements are available in this doc.
Also, Windows Server 2008 has reached its end-of-life in January 2020.
So in your case, the best scenario is to deploy a new server with the supported Windows Server version and with Plesk Obsidian being installed and then to migrate on it using these instructions.
Thanks Anzhelika, I thought that might be it.
Is it a fact that Plesk version 17.5.3 will not install on Windows 2008 R2. I got this error message when I tried to upgrade from 11.5.30 to 17.5.3, but I also got an option to contimue which I did not try. ERROR/Warning:

Plesk pre-upgrade checking...
WARNING: Starting from Parallels Plesk 12.0, MyLittleAdmin 2000 is no longer supported.
ERROR: The system was unable to find the specified registry key or value.
Proceeding with installation or upgrade without resolving the issues that were found can corrupt your data.
I confirm that I want to continue, regardless of the issues found.

Can I continue? What is the risk if I do. Where do I get a registry key?
Thank you
Hello John Lloyd
The error
ERROR: The system was unable to find the specified registry key or value.
means that some Plesk-related information in the Windows registry is missing or corrupted. Sometimes this happens due to previously failed updates.
In case proceeding with the upgrade may cause Plesk inaccessibility. Additionally, Windows Server 2008 R2 support was dropped by Microsoft this year, so Plesk installations on this OS are no longer supported.
The recommended approach in your case is to prepare a new server with the supported OS (Windows Server 2012 or newer) and migrate domains there using this guide.

Hello webmaster
This means that the key you have isn't suitable for the type of server you use.
