How can a new license key be generated after upgrading to Retool Business?

Hello, I have some question regarding the license key and Retool Business. Our customer upgraded from the original Retool Free to the Business plan, but the "Your license key" displayed on https://my.retool.com is the same as the one for the original Retool Free, and no new license key has been generated. Is this normal? Can we use the same license key to install Retool Business on another computer B? If so, does the original computer A, where Retool Free was installed, become unusable, and will the database be deleted? If that is the case, how can we generate a new license key to install Retool Business on another computer B? Our customer urgently needs guidance on installing Retool Business on another computer, so we appreciate your prompt response. Thank you very much!
