If you have installed the Evaluation version of Microsoft Lync Server 2010, you will eventually need to update that installation a licensed copy of the software; that's because the evaluation version expires 180 days after it was installed. However, you will not need to completely uninstall the evaluation version and then install the licensed version. Instead, after you have obtained a valid licensing key, you can update the evaluation version of Lync Server 2010 by carrying out the following procedure on each computer acting as a Lync Server Front End Server, Director, or Edge Server. Note that you do not have to update computers carrying out other server roles, such as a Monitoring Server or Archiving Server.

The Get-CsServerVersion cmdlet will analyze the local computer and report back one of the following:

  • That the Lync Server volume license key has been installed on the computer, meaning that no updating is necessary.

  • That the Lync Server evaluation license key has been installed, meaning that the computer must be updated.

  • That no volume license key is required on the computer. Updating from the evaluation version to the licensed version is only required on Front End Servers, Directors, and Edge Servers.
