Change SharePoint 2010 Web Application Port Number

Recently, I had to move an existing SharePoint 2010 web application from the default port to a new port.  This is relatively easy to do but does require two steps.  The first is a change made in Central Administration; the second is done in IIS Manager.  Here are the steps I followed:

Step 1

In SharePoint Central Administration:

·         Click Application Management

·         Click Configure Alternate Access Mapping

·         Click the web application you are trying to alter

·         Change the port number by altering the URL; Save

Step 2

In IIS Manager:

·         Select the SharePoint site that corresponds with the web application above

·         Click Bindings…

·         Select the current port; click Edit; change the port number; Save
