Upgrading to a different server product
If you wish to upgrade for example from NoMachine Workstation to Terminal Server , either because you want to increase the number of sessions, or simply because you want to get access to the features supported by this product, you will have to purchase a new subscription and receive new license keys. Just replace your current license files with the new ones in your NoMachine installation. You will find server packages tailored for your new subscription in your Customer Area.

Upgrading the subscription to Premium Support option
If you have purchased a subscription and wish to change to Premium option, you will need a new subscription. If you are keeping to the same product, e.g you are using NoMachine Terminal Server Subscription and wish to upgrade to NoMachine Terminal Server Premium Subscription, you can still use the same software and the same subscription files.

In either case above, please contact the sales team to find out what the cost will be to upgrade.
