Upgrading

To upgrade your Puppet Enterprise deployment, you must upgrade both the infrastructure components and agents.

CAUTION:

Major primary server OS upgrades (such as Ubuntu 18.04 to 20.04) require Backing up and restoring PE.

Major agent OS upgrades require reinstalling the puppet-agent package (as explained in Installing agents) and reinstalling any Ruby plugins/gems that were added at /opt/puppetlabs/puppet/bin/gem.
