I have a mac mini server that came with snow leopard server. My uses are relatively simple so I've never really used the server functionality. This has been fine, until now. I'm trying to upgrade to Lion, but the installer won't proceed unless I also buy the $49 Lion Server add-on. Since I have no real need for the advanced server features, I prefer not to pay an extra $49. Not to mention that the reviews on the App Store have been poor for the server. Is there a way to hack around the restriction in the installer that would allow me to upgrade to Lion? The restriction seems to be entirely a policy one and not a technical one, since upgrading from Snow Leopard Server to Lion Server requires running the Lion installer first anyway, meaning that it can successfully install on the Snow Leopard Server system.
