This can be an excellent cost savings move for enterprises that need to move up to enterprise plus licensing in order to keep consistency in your enterprise licensing model (since the enterprise version goes away after this year as a purchase option).

Instead of paying $800 some dollars per proc for enterprise plus licences per proc, you can pay only $145, which is good for two months. Then your current enterprise SnS are automatically upgraded to the enterprise plus level at a prorated value of .8226. See your VMware reseller for more!
