Upgrade Chef


#1

Hi to all,
I have a chef environment that I would like to upgrade.
Chef Server: 10.12.0
Chef-clients: 10.14.4 on CentOS 5 (and a few clients with 10.18.2 on CentOS 6)

  1. Could/should I upgrade to chef server 11 and latest chef-client?
  2. Is there any documentation on the upgrade process?
  3. Could I also upgrade ruby version to 1.9?

Thanks!

IMO you should upgrade to chef 11 server and clients, and switch over to
the omni client and omni server. It will save you some pain on Cent. There
Is an Opscode blog post that goes over the process here:
http://www.opscode.com/blog/2013/03/12/5106/ . Many people, and myself,
have recommended this blog post that details the process
http://www.ducea.com/2013/03/05/howto-migrate-to-chef-11/ using a different
knife plugin.

If you use the chef omni installers then you don’t need to touch your
system ruby version.

Changes to be aware of when upgrading to chef11 are listed here:
http://docs.opscode.com/breaking_changes_chef_11.html
and more info on the attribute changes can be found here:
