Hi I’ve just upgraded a license from 50 to 100, but I have to licenses for 50. How do you decide which one to upgrade? 
I need this one upgraded xx59416 from my license list.
Please look into this?
Howdy,
I’ve applied your license upgrade.
Thanks for using Virtualmin!

Thx. The server still says 50 licenses, is there anything I need to do on the Server?
Howdy,
It normally should detect the update after a few minutes… though there is a Re-Check License option in the top-right of the System Information screen that you could click to force a re-check.
