Thanks to a nice email from co-worker Jeff it saves me time to write it myself and I am just copy and pasting his text onhere. We get many questions on howto upgrade from a trialkey to a production keycode. Below is the procedure to follow.
This should take care of the upgrade of keys. The only time I have seen issues myself is if the existing keys are something like MSDN keys instead of the Trial Version keys. MSDN keys cannot be upgraded!
The other thing to watch for is if the customer had originally installed 3.0 Professional Trial Version keys and now is trying to upgrade to 3.0 Small Business Edition production keys. The matrix for what can be upgraded is listed below.
