Multiple licenses but only one install


I'm pretty new to networking and tried Sophos Firewall for the first time.

I have only one install of Sophos on a VM. I believe I got a trial license which is now expired. On "My Sophos" account I have an additional license which is set to expire in 2999 since home use.

My question is how do I transfer the Sophos install from the expired trial license to the new one which appears on the account?
