This article describes how to install IGEL Universal Management Suite (UMS) 12 or upgrade your existing UMS installation and provides information on what should be considered during the installation / update.

IGEL Cloud Gateway (ICG) with IGEL OS 12 and IGEL OS 11 Devices

If you exclusively manage IGEL OS 12 devices, you may not need an IGEL Cloud Gateway (ICG) between your UMS 12 and your devices, regardless of whether the devices are inside or outside the company network. Whether an ICG is required or not depends on your particular use case or policy. See IGEL Cloud Gateway vs. Reverse Proxy for the Communication between UMS 12 and IGEL OS Devices.

If you manage remote IGEL OS 11 devices and want to manage also your remote IGEL OS 12 devices via ICG, ICG 12 is required.

If you manage your remote IGEL OS 12 devices without ICG and your remote IGEL OS 11 devices with ICG, you can use ICG 12 or ICG 2.x.

Please note the following, especially if you use any special policies or other components between the devices and the IGEL Universal Management Suite (UMS) or the IGEL Cloud Gateway (ICG):

  • IGEL OS 12 devices use TLS 1.3
  • IGEL OS 11 devices use TLS 1.2

The hardware requirements for ICG 12 are the same as for ICG 2.x with the exception that ICG 12 requires 4 GB of RAM instead of 2 GB, see:

  1. Download IGEL UMS 12 from the IGEL Download Server .

  2. Consider the installation requirements, see Installation Requirements for the IGEL UMS.
    If you are going to upgrade your existing UMS installation, see also Updating UMS.

  3. Install the UMS. Depending on your needs, you can install standard UMS, Distributed UMS, or UMS High AvailabilityInclude the UMS Web App and the UMS Console into the installation – both of them are currently required for the management of your UMS installation and devices. 

    Information on how to install the UMS can be found under:

    You can update to UMS version 12.01.110 or higher from

    • UMS 6.x

    If you participated in the program for validation and testing of IGEL OS 12, you can also update to UMS 12.01.110 from

    • UMS 12.00.900
    • UMS 12.01.x

    Before the update, it is always recommended to make a backup of your current system. For details on how to create backups, see Creating a Backup.

During the installation / update on Linux, you have to confirm or enter the IP address of the UMS Server. If you do not adjust the IP address, the web certificate of your UMS Server may contain the wrong IP, which results in problems with device registration. See Invalid Web Certificate and Errors by Device Registration after the Installation of the IGEL UMS 12 on Linux.

For Update Installations Only

  • As of UMS 12, MDM feature is no longer available. Cancel the upgrade to UMS 12 if you still need the MDM feature:
  • Only if you have a Distributed UMS installation: During the update installation, it will be checked whether only one UMS Server is running and the others are stopped. If not, stop all UMS Servers except one and proceed with the update; otherwise, you risk losing data. After the update on this server is complete, you can update the remaining UMS Servers, either simultaneously or one after another. But see also Known Issues UMS 12.01.110.

UMS 12 Communication Ports

If you are going to make network changes, consider the following ports and paths:

For more information on UMS ports, see IGEL UMS Communication Ports.

The web server port (default: 8443) can be changed under UMS Administrator > Settings. If you do not configure the Cluster Address, it is recommended to change the port before registering any IGEL OS 12 devices. This is due to the fact that the already registered IGEL OS 12 devices won't be manageable anymore after the change of the web server port if no Cluster Address is configured. In this case, you will have to register these devices anew.

The FQDN and port of your external load balancer / reverse proxy must be specified in the UMS Console under UMS Administration > Global Configuration > Server Network Settings > Cluster Address. Information on the Cluster Address can be found under Server Network Settings in the IGEL UMS.

It is recommended to check your rights since UMS 12 has new permissions, e.g. UMS Console > System > Administrator accounts > New / Edit > General - WebApp > App Management for managing IGEL OS Apps. See General Administrator Rights and Important Information for the IGEL UMS Web App.
