Upgrade CUCM 9.1 to 10.5 - Procedure (No Prime Collaboration Deployment)

So with the introduction of Cisco Prime Collaboration Deployment, now upgrade any of your UC applications its easier and quicker than before. One of the big advantages that I see with this new product is that the product can have control of the overall infrastructure, starting from VMware all the way to the UC applications. For a better understanding of this product you can use the following link: (http://www.cisco.com/c/en/us/td/docs/voice_ip_comm/cucm/pcdadmin/10_0_1/CUCM_BK_U9C58CB1_00_pcd-administration-guide-1001.html) - The previous is the one for version 10.x – I don’t see too many changes from version to version.
