I have three JSS servers - one is my play one (development). Then we have test with about 30 users on it. Anything I'm going to deploy to the masses goes there first. Finally we have our Production JSS. Any changes to Test or Production need to go through change control.
I wrote a little tool to change which JSS server my Mac is enrolled in and thought I would share it here. https://dl.dropboxusercontent.com/u/6303870/SwapMyJSS.1.31.dmg
It's intended to be used in a test lab where you need to change which JSS server a Mac is enrolled in. If you only have one JSS server, you do not need this tool!
To use it, create an Enrollment Invitation on each of your JSS servers and get the enrollment key. I recommend you set it to not expire and allow for multiple uses.
Then in the Prefs window of SwapMyJSS, enter the server name and enrollment key. I hope this help. The computer running SwapMyJSS should already be enrolled in one of the JSS servers. See the readme for more info.
Thanks
Todd
