title: How to compare vm Templates between two VMware vsphere environment?
body: <p>I'm using two different vsphere environments for deploying my application. I'm using a template of pre-installed RHEL, and from time to time I want to update the template on both environment (usually for security reasons). While I'm updating one template and export-import to the other vsphere.</p>
  
  <p>I tried to find some data to compare the templates (to ensure that I'm really use same one) such a checksum, without success.</p>
  
  <p>To make it difficult my two vsphere are not in the same version, one is 5.1 the other is 5.5.</p>
  
  <p>Thanks </p>
