Can I upgrade Chef Server 11.1.3 nodes to chef-client 12.5.1?

We are running Open Source Chef Server 11.1.3.

Can we upgrade our server 11.1.3 nodes to chef-client 12.5.1?

Would anything prohibit me from making use of the new custom resource model in my cookbooks?

We do plan to upgrade to chef-server-core 12.2.0-1, but haven't finished testing yet.

Thanks!

When chef client 12.0 has been release the comaptibility with chef server 11 was said to work (I personally had problems with chef-server 11.0.8).

There's no compatibility matrix as far as I know.

If a chef-client 12.5 can work with your server, the custom_resource won't be a problem, the server only store cookbooks and don't run them, so it should be ok to use them in your cookbooks.

Edit to complete: Quote of this message from Kallistec on the chef mailing list:

Each product is supposed to work with +/- 1 major version of the other. Two caveats:

  • there will be bugs, so if there’s a bug in 11.0.8 and it’s not fixed until 11.1.x, you would need to upgrade
  • When new functionality is added that requires both client and server to function, we don’t make any commitments about backporting. For example, the new policyfile features aren’t going to be backported to Chef Server 11.
