If you have used the UMS's integrated webserver to distribute the firmware updates, the updates that are still required should be manually transferred to the new server or the FTP server (if you configure it as the destination for the update files, see Universal Firmware Update). See also How to Detect Which Files Are Synchronized Automatically. Or you can simply download the required firmware updates anew.
Defining the Database Connection
Stop the Windows service IGEL RMGUIServer on the old UMS Server.
In the UMS Console, go to UMS Administration > UMS Network and check the items Server and Load Balancer if the complete UMS HA Extension has been selected for installation. Check if there is an entry for the previous UMS Server among the listed components. If so, delete it.
Transferring or Registering Your UMS Licensing ID
Transfer the UMS Licensing ID of the previous UMS installation to the new server. Alternatively, you can register the new UMS Licensing ID, which was created during the installation of the HA server. For detailed instructions, see Transferring or Registering the UMS Licensing ID.
The configuration of the DHCP tag and the DNS alias is not a setting that can be made within the IGEL software. You must configure these within your individual network environment on the corresponding DHCP and DNS servers.
