Hi All,

We are trying to unistall the portal. Does anyone have any information on how to do this.

I am assuming you are talking about the CRM 4 version of the portal, and not the CRM 2011 version.  One of the features of CRM 2011 is the new solution model, and that solution model supports uninstalling of managed solutions.  Unfortunately, for CRM 4, there is no easy way to uninstall the solution.  The approach for CRM 4 is to remove each entity one by one.  You have to remove the entities in the correct order because of the dependencies between them (for example, you have to remove web page before removing website.  You should have no problems removing them one at a time.  I would start by removing the workflows first.  When you get the custom entities all deleted, you can then deconfigure the changes to contact and campaign.  To do that, remove all references to the custom fields in the forms and views, publish your changes, then remove the custom fields.  As you can see, this is quite the process, and is the base premise of why the product team invested so heavily into a solution model for CRM 2011.
