Episerver 7.5 and higher support Windows 2016 and 2019 https://world.episerver.com/documentation/system-requirements/
However you might want to consider upgrade to latest version (11.20.2 at this time) to benefit from new features and improvements
Episerver has never tested v7.5 on Windows 2016 and its not in the official supported list of OS's: https://world.episerver.com/documentation/archive/system-requirements/?p=203155
I would personally recommend upgrading to the latest v11 version and am curious to know why you want to only upgrade to 7.5 from 5.2 instead of upgrading all the way to the latest version?
We are thinking of migrating one of our EpiServer CMS 5.2 implemetation to 7.5
From the requrements documetation it seems like EpiServer 7.5 officially supports Windows 2012 R2 & Windows 2012.
Unfortunately, all our infrastructure has moved on to Windows 2016.
Hence can someone confirm that we will get the same official supports as before if we move to Windows 2016 ?
