title: Import orders on Magento
body: <p>I've recently upgraded my Magento store from 1.4.2 to 1.7.</p>
  
  <p>I did this upgrade on a local machine as the online store was still running. As an effect, I had customers making orders on the online database while I was upgrading the local database to 1.7.</p>
  
  <p>Now I need to merge the orders from both databases so I don't lose any order in the backoffice.</p>
  
  <p>I've looked into some extensions but they're all paid.</p>
  
  <p>How can I achieve this without having to pay for an extension I'll only use once?</p>
