How should I upgrade Puppet and Facter?
The best way to install and upgrade Puppet and Facter is via your operating system’s package management system, using either your vendor’s repository or one of Puppet Labs’ public repositories. If you have installed Puppet from source, make sure you remove old versions entirely (including all application and library files) before upgrading. Configuration data (usually located in /etc/puppet or /var/lib/puppet, although the location can vary) can be left in place between installs.
