Easiest would be to configure everything on the new server, export/import the configuration settings using https://www.ez-pc.net/windows/how-to-export-and-import-the-ip-relay-list-on-an-iis-smtp-virtual-server/.
That's the IIS configuration part, do all printers and applications use a DNS alias? If yes, change the cname to point to the new server or change the ip-address if it's just a A-Record. If you have things configured to use a static ip-address... Then shutdown/disconnect the old server and change the ip-address on the new server to the old ip-address. Short downtime moment, test a few things and if everything is ok you can delete the old server. If it fails, change the ip-address on the new server again and turn on the old server and see if you can prevent the issue before switching again.. In a nutshell 🙂
