Upgrade from 'Free for personal use' to 'Core Edition'


With UCS-4.0-1 errata158, the new UCS Core Edition was announced. Every “Free for personal use” license can easily be migrated to the UCS Core Edition.

  • For already fully licensed domains nothing changes.
  • Newly installed systems will automatically use the new license and will benefit from it automatically.
  • Previously installed systems, which have not been activated yet through registration for the Univention App-Center, will be upgraded automatically.
  • For registered systems, the activation must be repeated to get a new license. The exact procedure is described below:

Please note: UCS 4.0-1 errata158 or newer is required to use the UCS Core Edition. Please upgrade your UCS system first if you use an older version.

  1. Login as user “Administrator” to the UCS Management Console on the UCS Domaincontroller Master.

  3. Open the same menu again and this time navigate to “Activation of UCS”:

  4. Enter your email address and press “Send license”. A new page for importing the license is displayed.
