We have SharePoint 2013 on 2 Servers and both are installed on Windows Server 2012R2. The ADFS and WAP Servers are also installed on Windows Server 2012r2. SharePoint 2013 cannot run on OS 2019 as per the MS Document, but I want to know if I can upgrade the ADFS and WAP Servers OS to 2019 and will SharePoint work properly..
Our AD's are on OS 2012r2 but we will upgrade them soon to 2019...
Thanks,
Sheldon
