File config-files-warning.txt of Package janus-gateway
If you are upgrading from a version of Janus Gateway prior to 0.6.0 you may be using the old INI format for the configuration files at /etc/janus. If that's the case, please make sure you convert those files to the new format, based on libconfig. The tool janus-cnfconv is provided as part of this package to ease the migration.
