I have a client who bought SA for their SBS server 2003. The SA term expires in 30 days. They don't really want to upgrade now, as everything is working perfectly and they have no need. However, they would like to have the option to upgrade in the future. Is it possible to execute an SA upgrade, without actually installing the upgrade? In other words, can they exercise their right to upgrade now before the term expires, but then simultaneously exercise their downgrade rights and keep running the 2003 box, while having the 2008 license in their pocket?
