Have to upgrade our environment's workstations from Windows 10 Enterprise Edition 1809 (current build 17763) to 1903 then 1909 and ultimately 2004. Unfortunately I cannot even get the first upgrade to 1903 going successfully. I believe I have everything setup correctly on WSUS:
On WSUS, Options> Products and Classification :
(checked) Windows 10
(checked) Windows 10, 1903 and later
(checked) Windows 10, 1909 and later
(checked) Upgrades
Updates > All updates:
(Approved) Feature update to Windows 10 Version (business & consumer), version 1903 en-us x64
(Approved) Feature update to Windows 10 Version 1909 x64 based system 2019-11 via Enable package
Any upgrade I attempt to approve/apply is categorized as not applicable. I know WSUS is communicating because we are able to do our monthly updates. Any ideas what I'm doing incorrectly?
