Unfortunately, it isn’t possible to combine several individual licences into one larger licence.
However, you can upgrade one of your existing licenses to the desired license tier in the customer portal and cancel the other license.
Afterward, you can replace the license key on the websites that were previously connected to the canceled license. Your existing settings will remain unchanged.
You can find the available upgrade options in the customer portal https://service.borlabs.io/login in the licence details under the "Upgrades" tab.
