Hi Shawn, We went through this with Puppet 2.6 and PE 2.0. It wasn't particularly painful, though we did have Puppet Labs PS on site to help. For a standalone installation of Puppet I wouldn't consider that necessary, but if you want to add HA, multiple masters, or other complex configs you may want to consider it. It depends on whether you've already done those things in your existing Puppet install. At a basic level we configured our CA's, had our old Puppet Masters configure the clients to use the PE Masters, then had the PE Masters install the PE Agent. It was easier than running the PE Installer everywhere. If your existing Puppet infrastructure is too new you may not be able to go this route since the agents can't be newer than the master. Planning elements: if you're not using the Puppet Dashboard already you'll want to think about whether the MySQL server and PE Console services need to be HA. If you're going to use the PE Console as an ENC then I'd vote yes, since the ENC becomes a single point of failure regardless of how many Masters you have. You'll also want to read up on the Puppet Certificate Authority since you'll be dealing with your existing certificates one way or another. If you're not using MCollective it's one of the nice things about PE since it comes pre-configured and you don't have to learn how to configure ActiveMQ and friends right away. Unfortunately it doesn't run arbitrary programs so in order to extend it to do new things you'll have to read up on a little bit of Ruby. All-in-all the complexity of it mostly depends upon the complexity of your existing environment. As far as downtime goes, you can easily run them side-by-side (managing different clients obviously) so you shouldn't need to worry about having completely unmanaged systems. -- You received this message because you are subscribed to the Google Groups "Puppet Users" group.
