Re: [Puppet Users] Upgrading from 0.25.1 to 3.7.4

Hunter:
Thanks for the bit about the classes.txt. file. That was exactly what I was
needing.

Martin:
I am in the process of doing that work now. I have been playing with
Foreman as a front end to be able to use the smart parameters to clean up a
lot of classes. The import and inherits are plentiful!

Hi James,

a horrible task (I am still busy at a customer upgrading the puppet DSL code 
from 2.7.23).

You want to get rid of:
- non-scoped variables (in manifests, modules and templates)
- import in class files

You might need to:
- clean up node classification
- rewrite classes to have parameters
- rewrite self developed facts, functions, types, providers

And you definitely want to have rspec tests in place.

Good luck.

Martin

P.S. I know of at least one installation where they did not upgrade, but a 
complete rewrite and a new puppet master.

Wow, that's a pretty big jump :).

It's not super terribly helpful, but each node should have a "classfile"
that is often in the $vardir/classes.txt or $statedir/classes.txt that
contains all the classes a node has applied to it in the last puppet run. I
think `puppetd --configprint classfile` on a node will mention where it is.

[Puppet Users] Upgrading from 0.25.1 to 3.7.4

[James Perry]

I have been tasked to upgrade puppet 0.25.1 to 3.7.4.  There has been a lot 
of past admins tweaking this puppet server and most of the existing modules 
are all ad-hoc creations. I want to ensure I do not miss any expected 
dependencies, but I also do not have months to manually traverse the entire 
Puppet site.pp file by hand.

Is there some tool, script or puppet command that will show me a quick 
digestion for each node as to what modules it includes and inherits? 

Thanks!
