Before upgrading a production Airtime server, you should back up both the PostgreSQL database and the storage server used by Airtime. This is especially important if you have not already set up a regular back up routine. The extra back up is a safety measure in case of accidental data loss during the upgrade, for example due to the wrong command being entered when moving files. See the chapter Backing up the server in this book for details of how to perform these back ups.
If you have deployed Airtime using the Automated installation method, you can upgrade in the same way. A new Airtime package available in the Sourcefabric repository can be installed with:
$ sudo apt-get update $ sudo apt-get upgrade
If you have used the Manual installation method, you should repeat the installation steps of downloading and unpacking the tarball to an installation directory, changing to that directory, and running the airtime-install.php script. The installation script will detect an existing Airtime deployment and back up any configuration files that it finds.
After the upgrade has completed, you may need to clear your web browser's cache before logging into the new version of the Airtime administration interface.
