title: Update changes from Developement instance to Production instance in Odoo
body: <p>I have 2 instances of Odoo v9 running in the same server (Ubuntu 14.04). I want to make changes (install modules, change source code or anything) in the developement instance and after confirming they are OK, move the changes to the Production Instance. Is there anyway of doing that without repeating the whole process of development?</p>
  
  <p>Thank you.</p>
