Upgrade to Gluu Server 4.2#


The Gluu Server cannot be upgraded with a simple apt-get upgrade. You will need to either use our in-place upgrade script or explicitly install the new version and export/import your data. Find the existing version below for upgrade instructions to Gluu Server 4.2.


  • Before upgrading, make sure to back up the Gluu container or LDAP LDIF.
  • Upgrades should always be thoroughly scoped and tested on a development environment first.
  • This upgrade process only upgrades versions 4.0.x and 4.1.x. To upgrade from a previous version, first upgrade to 4.0.
