Step 3: Join computers to the new Windows Server Essentials server
Applies To: Windows Server 2016 Essentials, Windows Server 2012 R2 Essentials
The next step in the migration process is to connect client computers to the new server running Windows Server Essentials.
You can skip this step for computers that are running the Windows XP or Windows Vista operating systems. The Windows Server Connector software does not support computers that are running Windows XP or Windows Vista.
Before you can join a client computer to the new Windows Server Essentials server, you must disconnect it from the Source Server by uninstalling the Windows Server Connector software on the client computer.
To uninstall Windows Server Connector on a client computer
From a client computer, open Control Panel, and then open Programs and Features.
In the list of programs, right-click the Connector application that is running on your computer.
The Connector application can be Windows Small Business Server 2011 Essentials Connector, or Windows Server Essentials Connector, depending on which version of Windows Server Essentials the client computer was connected to.
To reconnect a client computer to the server
Sign in to the computer that you want to connect to the server.
If this computer has multiple user accounts, sign in by using the user account that has documents, pictures, and personal preferences you want to keep after you connect the computer to the server.
Open an Internet browser, such as Internet Explorer.
In the address bar, type http://<servername>/Connect, and then press ENTER.
Follow the onscreen instructions to join the client computer to the new Windows Server Essentials server.
You have joined your client computers to the new server running Windows Server Essentials. Now go to Step 4: Move settings and data to the Destination Server for Windows Server Essentials migration.
