Hello,
Technically the procedure is the same as any other licensed SQL Server edition. But to obtain the media and license of the new SQL Server version as a benefit due to the embedded maintenance, you may have to call Microsoft Licensing at 1-800-426-9400, Monday
through Friday, 6:00 A.M. to 6:00 P.M. (Pacific Time) to speak directly to a Microsoft licensing specialist. You can also visit the following site for more information and support on licensing issues:

Hope this helps.
Regards,
