If you used Razor in a previous Puppet Enterprise (PE) environment, upgrade Razor to keep your PE and Razor versions synched.
After a PE upgrade, your
pe_razor module continues to operate normally, but we recommend upgrading Razor as soon as possible to avoid unintended effects.
Note: If nodes are actively provisioning during upgrade, provisioning might fail. You can resume provisioning after
pe-razor-serverrestarts and – for upgrade from 3.8.x only – after a Puppet run completes.
The upgrade process varies by PE version.
Upgrade from 3.8.x to later versions
An upgrade script handles upgrading Razor from PE 3.8.x to any later version. The script carries out these tasks:
- Performs pre-verification, including checking that:
- The script is being run as root.
puppet-agentclass is installed. The script exits if not.
- The Razor node has sufficient disk space available. The host’s disk space must be at least three times the size of the Razor database.
- Shuts down the

Before you begin
Follow these steps to prepare to upgrade:
Verify that the Razor server has access to the internet.
Tip: If you want to upgrade Razor offline, follow the instructions here.
Verify that no services are active on the agent or Razor server. Services are stopped during upgrade.
Ensure that no custom or modified tasks, brokers, or hooks exist inside
/opt/puppetlabs. If they do, move them to a directory in the appropriate class parameter (
hook_path) of the
pe_razorclass. By default, the paths for these objects are:
- Tasks –
- Brokers –
- Hooks –

Run the upgrade script
The Razor upgrade script upgrades your Razor server node to match the version of PE you’re running.
- SSH into your
razor-servernode, then run
sudo bash /opt/puppet/razor/upgrade/upgrade.bash.
Upgrade from 2015.2.x or later
Upgrading from 2015.2.x or later is a mostly automated process that replaces the software repository, installs software packages, and migrates the Razor database.
Upgrading to 2016.4 or later requires manual migration of any custom configuration from your config.yaml file to class parameters in the
Before you begin: If you’re upgrading to PE 2016.4 or later and you’ve modified your config.yaml file – for example, by changing
protect_new_nodesor customizing tasks, brokers, or hooks – make a note of the modified settings.

Tip: You can run
razor --versionto verify that the upgrade was successful.
