Qliksnese enterprise upgrade from Windows OS 2012 to OS 2019

Is it possible to run a 7 server Qliksense enterprise configuration with mix Windows OS levels.

We can't upgrade them all at once so we would like to upgrade a few each week from Windows 2012 R2 to Windows 2019.

That means we would be running the enterprise cluster with 2 different Windows OSs for a short time.

Do you expect that this will cause any issues.

We are currently using QlikSense Nov 2020 enterprise.

I have enclosed a diagram of our current environment.

Thanks

Hi @markdur101,

You may have issues with mixed operating systems due different DLL files or different.NET versions, or you may not have any issues at all. One thing to note is that Qlik Sense version Nov. 2020 reached end of life for support in Nov. 2022. See Qlik Knowledgebase article Qlik Sense Enterprise Server for Windows product lifecycle for more details. 

Suggest that you plan on upgrading the Qlik Sense Enterprise version to a supported build as soon as possible.
