Upgrade From Free To Lifetime?

Hi,



I'd like to set-up a demo site using the “free” version to show client before he decide to proceed. If so, I don't really want to have to install and configure a lifetime version from scratch if he decides to proceed.



Is it therefore possible to upgrade the software from free to lifetime without re-installation and re-configuration (but obviously buying a license) ?

Nevermind, I’ve found it is possible.
