Preparing New Servers

  1. Verify that each server can "see" the other servers via the network.

    All UMS Servers and UMS Load Balancers must reside on the same VLAN. Network traffic must be allowed over UDP broadcast port 6155, and TCP traffic and UDP broadcast traffic over port 61616. For more information on UMS ports, see UMS Communication Ports.

    Note: IGEL UMS Server HA is not supported in cloud environments like Azure / AWS as they do not allow broadcast traffic within their networks.

  2. Verify that the time on all servers is synchronized.

    To avoid problems with your HA installation, make sure that the time on the servers of the HA network does not differ by more than one minute. After each manual time reset, the HA services on the relevant server must be restarted.

  3. For Linux systems, make the directory /root writable for the user root.

Preparing the Existing System

Tip

The move provides an opportunity to remove any UMS database data which are no longer used. For example, you can

  • delete endpoint devices that no longer exist
  • delete profiles that are no longer used
  • remove files and firmware updates that are no longer needed

It is highly recommended to create a backup before carrying out the cleanup (as a backup of the system running) and another one after the cleanup. 

  1. Create a backup before performing the move:
    • For the embedded database: Create a backup using the UMS Administrator tool, see Creating a Backup. Include all options in the backup.

    • For external database systems: Use the backup procedures recommended by the DBMS manufacturer. For the backup of server configurations, use the UMS Administrator tool, see Creating a Backup.
  2. Save the following files, e.g. to a storage medium that can be accessed during UMS HA installation:

    Certificates

    • [IGEL installation directory]/rmtcserver/* (includes the tc.keystore file, which is necessary for the communication with the endpoint devices)

    • [IGEL installation directory]/rmclient/cacerts

    • [IGEL installation directory]/rmguiserver/cacerts

    • [IGEL installation directory]/rmguiserver/irm_keystore

    Device licenses
    (up to UMS 6.07; as of UMS 6.08, licenses are included in the database)

    • [IGEL installation directory]/rmguiserver/webapps/e08ce61-d6df-4d2b-b44a-14c1ec722c44
    Files and firmware updates
    • [IGEL installation directory]/rmguiserver/webapps/ums_filetransfer
  3. Create a backup of the UMS Licensing ID using the UMS Administrator tool. For detailed instructions, see Transferring or Registering the UMS Licensing ID.
