Microsoft is allowing certain customers to extend existing versions of license agreements to the cloud.

On its website, Microsoft said the license mobility "will provide customers the flexibility to deploy certain server applications with active Software Assurance on-premises or in the cloud, without having to buy additional licenses."

This includes Exchange, Lync, SharePoint, SQL Servers and Dynamics CRM.

License mobility has been introduced to support migration to the cloud.
