Upgrading from free version to licenced version

Upgrading from free version to licenced version

Hello,
 
Currently I am doing a proof of concept for OpManager using the free version (I chose to use the free version as I didn't know if I would be able to complete the proof of concept within the 30 day trial period for the other version).
 
All is looking pretty good actually; which got me wondering whether there is any issue with migrating from the free version to a licenced copy? Is it something as simple as adding in a registration key, or will I need to go through and reconfigure everything from the ground up after uninstalling the free version and reinstalling the licenced version?
 
Thanks for your help.
Regards
Troy
