On the various websites it is stated the server doesn't require a special procedure in order to install it on another computer. The only thing you need to do is to activate it on the new computer with the serial ID. During the activation process, the old serial number will be deactivated and the new one will be used instead. Make sure you have an active Internet connection because this is a must for the activation. Secondly, if you still have the software installed, go to Help > Contact and the customer service. I have seen that for these type of applications, you benefit from tech support for any of the operations related to the server migration, activation, purchasing, etc.
