Been through a similar upgrade myself. The first step would be to spin up a new puppet master running Puppet Server. You can copy over the SSL dir from your old/current master to avoid SSL errors on the agents. For testing you'll want to make sure your manifests work correctly using the future parser, that can be enabled in the puppet.conf file on the agents. Setting up a separate environment for testing is also recommended.
Puppet Server will work with 3.7 clients so once you have a manifest that compiles correctly you can just point the agents to the new master's IP.
