Puppet Minor Upgrade

[Peter Krawetzky]

I need a clarification on a comment in the puppet upgrade doci.  Does this mean (last sentence below) I can upgrade the puppetdb servers before the puppetservers and puppet agent?  It's the "nodes" comment that has me confused.  I take that as it can go before anything.

A minor upgrade is an upgrade from one Puppet 4 release to another. The order in which you upgrade packages is important. Always upgrade puppetserver on your masters before you upgrade agents. You can upgrade PuppetDB before or after you upgrade other nodes.
