Dynamics CRM 2011 upgrading from trial license

I often see on the CRM forum questions how to upgrade CRM from a trial installation into a full licensed environment without the need to re-install CRM, so decided to create a quick post on how to do this and where to find the newly purchased CRM license key.

Registry key
If you purchased the full license, Microsoft will provide you with a Media download link, so you can download the installation DVD. The key is not provided by the sales assistant's because the registry key is now built-in in the media. However you can retrieve this key form the DVD on:

D:\Server\amd64\License.txt

Upgrade Trial License
Open deployment manager:

PowerShell

You can also set your new license key with PowerShell, below are the commands to do this:

To activate CRM PowerShell commands type the below command:
Add-PSSnapin Microsoft.Crm.PowerShell

To set the new CRM key run:
Set-CrmProductKey -ProductKey [string]

To get your current version:
Get-CrmLicenseProperty
