<b>Upgrading ArcGIS</b>

Our Webhead team updated our client's ArcGIS installation this past week. We were able to upgrade the following software for the client from version 10.5.1 to 10.6.1. The upgrade took approximately about 3 hours for myself and the senior developer on the website.
<ul>
 	<li>ArcGIS Desktop</li>
 	<li>ArcGIS Server</li>
 	<li>ArcGIS Web Adaptor (IIS)</li>
</ul>
Most of the installation dealt with downloading the license software through the MyESRI interface

And then installing the software packages in order. We did have to authorize the Extensions for the server as well. For the Web Adapter, we had to unregister the current URL, uninstall the Web Adapter and then re-install it. Then we had to re-register the Web Adapter URL.

As a closing note, I will say that the ESRI Support Team provided excellent assistance. You don't want to tackle this product without their support at the ready.
