Due to changes made late last year, Microsoft software such as Exchange, SQL Server, SharePoint, Windows Server and others can now be migrated from server to server without users violating their licenses, Yuen said. The importance "of license portability, we get that now," Yuen said. That portability is true, even if VMs are being moved from server to server using VMware's V-Motion live migration tool. Microsoft will also now fully support applications running inside VMs from partners such as Novell Inc., Red Hat Inc. and Citrix Systems Inc. "If you have a Red Hat issue, we will attempt to solve it and then escalate it with Red Hat if we can't," he said."
