Puppet users - Nov 2013 - Upgrade from Puppet 2.7.20 to latest !!!

Dear All,

I have my puppet servers and clients on puppet 2.7.20 and I am planning to
upgrade to the latest version.

But the problem is that I have a lot of modules (downloaded from forge and
few of my own) which used by hundreds of puppet clients.

I need to know
1) Will the functionality of these modules get affected after this upgrade ?
2) Other than ritual of being on the latest verison, are there actually any
benefits of upgrading?
3) Any other precautions that I should take during / before / after the
upgrade ?

Thanks & Regards,

Rakesh K.

There might be some impact. A good thing is to already have cleaned up
all deprecation warnings on the master, before going to 3..

If you want to be really sure, compile your catalogs once with 2.7 and
then once with 3.3.2 and diff them so you might get an idea what could
go wrong. If your modules are in a good shape, then the you likely
won''t anythig.

There is Volcane''s catalog-diff for that and there is a wrapper script
that can assist you doing that:

But you will have to investigate some time to!
