We currently have an AD FS 2012 farm setup that it's working fine. We would like to setup a new AD FS 2016 Farm. Can we have two separate ADFS farms in the same Active Directory domain? Would it cause any issues? Should the second farm use different certificates or can we use the same wildcard certificate for the second farm?
We want to make sure the new farm will not cause any issue with the old farm that can cause a production issue.
