To take benefit of new features provided by AD FS 2016/2019, an AD FS 3.0 deployment must be upgraded following specific steps to avoid service disruption.

The upgrade procedure is pretty straightforward and it doesn't require any service downtime.

The steps involved in the upgrade procedure are the following:

  • Add a new Windows Server 2016 and install the AD FS role
  • Configure AD FS service in the new server
  • Move the FBL to the new server
  • Remove old server from the AD FS farm
  • Upgrade to FBL Server 2016

Although the upgrade procedure uses Windows Server 2016 as a reference, steps are similar also for the upgrade to Windows Server 2019.

 

Install the AD FS role to the new server

From Server Manager click Manage > Add Roles and Features. Click Next to begin with the role installation.
