Updating the Installation of an HA Network

General overview

To update the UMS High Availability network, proceed as follows:

  1. First update the UMS High Availability network to a new version, server per server.
  2. Afterwards, update other components like separate load balancers or consoles.

While being updated, a server disconnects itself from the productive database and stores a copy of it locally. The last updated server will also update the schema of the productive database. After this, all other servers connect themselves again to the original productive database. In this way, all servers can be addressed by the thin clients at any time during the update process, e.g. to supply user-specific profiles (IGEL Shared Workplace).
