Upgrading from Vista Home Premium
Our office needs Vista Business at a minimum to be compatible with a new mail server we are adding. We have Home Premium now.
I wanted to run by our two upgrade options and make sure I'm not missing something.
My first option is to upgrade to Ultimate... apparently the only version Microsoft allows you to upgrade to from Home Premium. Pretty spendy at around $200 per. No OEM version offered either it seems.
The other option I have is to buy the OEM, full version of Business for $140 apiece, and replace what we have. The OEM version of Ultimate is $180.
I can't seem to find OEM upgrade versions, just full installs.
