Dear Sir,
Customer want to upgrade their existing Win2012R2 domain controller environment to Win2019. It has a standalone server joined to Win2012R2 domain currently.
`May I know if all of the Win2012R2 DC upgrade to Windows 2019 version. Do it has any issue on Win2012R2 ADFS server ? Will it continue work properly or need to perform corresponding upgrade? Any document mentions on it?
Regards,
Joe Tam
