Foreman migration without problems.

I just migrated my Foreman instances to 1.1 in production (I’ll writte later about nice new features on 1.1).

One of most important test I do before upgrading the production is the non regression of ENC output. What I mean is that I check that the new Foreman server sends the same YAML to the Puppet master during ENC lookup. I wrote a small ruby script (using the external controler script from Foreman community) wich compares YAML responses between 2 Foreman instances (ie: production and QA).

In order to support parameterized classes, Foreman changed a bit the YAML structure but this script supports this changement.
You can find it on my Github repo. You just have to change the 2 URLs of Foreman instances and set your login and password.

This script stop automaticaly if it founds a different node defintion between dev and production. This tool allow me to be more confident before a major Foreman’s migration.
