Title: RE: [chef] Moving from gem chef to omnibus

I found a fairly (but not completely) painless migration path to a different server is this:

 

- Set up the new server

- On the chef workstation, modify your client.rb to reflect the new server. You'll also need to delete (or rename) your client.pem file and add the validation.pem from the new server.

- upload all your cookbooks, databags, roles etc. to the new server. Note: if you used knife to edit a databag or node attributes, you will run into trouble here.

- On each client, delete /etc/chef/client.pem, add /etc/chef/validation.pem, and modify the /etc/chef/client.rb to point to the new server. If running Chef as a daemon, you should probably also restart the daemon. You can use the knife bootstrap mechanism to execute this script, or simply use ssh.
 

You may also run into issues if you use environments, and quite possibly in other situations I didn't see in my testing.
