  • (Recommended) - Create an up-to-date backup before upgrading your controller in the event any issues are encountered.
  • Existing UniFi controllers must be on one of the following versions in order to upgrade directly to this version:
    Spoiler
    • 5.10.20 and earlier 5.10.x versions.
    • 5.9.33 and earlier 5.9.x versions.
    • 5.8.30 and earlier 5.8.x versions.
    • 5.7.28 and earlier 5.7.x versions.
    • 5.6.40 and earlier 5.6.x versions.
    • Most earlier versions are also supported for direct upgrade, going back to 3.1.0.
  • Java 8 must be installed on the system hosting the controller software. Java 9 and later are not yet supported.
  • As of UniFi 5.9, if using Cloud access, the UniFi Network controller device requires outbound 8883/tcp to be open/unrestricted. Find up-to-date port requirements here.
  • Minimum supported device firmware for UAP/USW is 4.0.9, and for USG it's 4.4.34.
  • Microsoft Windows specific:
    Spoiler
    Users running 64-bit Windows should only have 64-bit Java installed. If you have 32-bit Java installed then we recommend uninstalling it.
  • Debian/Ubuntu specific:
    Spoiler
    • For Debian/Ubuntu users installing via our repo, please update your APT source (see HERE).
    • Currently we only support MongoDB 3.4. We're working on updating support before end of life this fall. We have instructions for Ubuntu users in our HC article HERE (see section 2.2).

 

Notes:

  • The initial database migration will take longer than normal. It is expected to see mongo using most, if not all, of the available CPU cycles during this process. Please be patient, this process could easily take 15+ minutes, depending on the amount of historical stats, as well as the system specs. As always, err on the side of caution, and make a backup before upgrading.

 

Controller bugfixes/changes since 5.10.20:

  • Fix IPv6 encapsulation sizing.
  • Fix pagination button type.
  • Fix remote syslog validation when logging to controller.
  • Fix various bugs with guest portal pre-authorization.
