Moving datasources to new server

I have an applications group who is hosting with CF9. At some point we'll be using the multi-server version and in the interest of setting up servers quickly and efficiently, my team is using Puppet and RunDeck to manage configuration files, installation of packages, etc. We'd like to cut out the Administrator Page of CF9 as much as possible. To that end, I know that if I use Puppet to copy neo-datasource.xml to a new server, the datasources will show up on the Admin page, but the connections fail. If I try to verify the (previously working) datasources, the Admin page shows driver failures. However, if I select "Edit" instead of "Verify" and just hit "Submit" (i.e., no changes to the datasource, just a lengthier version of "Verify"), the datasources come back OK and the connections come up. Can anybody explain this or what I need to do to get the datasources working in the first place without needing to go to the Admin page and hit "Edit" -> "Submit"?

Thanks!
