What to do with license key

We have a couple of systems running the ‘demo’ 6.3.0 and (since we are buying 2 more seats) QNX sent us new license keys to cover the time between the expiration of the demo and the receipt of the purchased licenses. My question is what to do with the key - has anyone out there updated a license before?

Thanks

QNX support showed me which menu to use - all done.
