I have purchased a new Parallels Desktop subscription while I'm having an active one already. Can I merge them?
You can extend an existing Parallels Desktop subscription with a newly purchased one.
NOTE: There are some limitations you should keep in mind. Let's say, you need to extend your subscription A with a newly purchased subscription B:
1) Subscription B should not be registered under any account yet. If you've already registered it under your account it cannot be used to extend other subscription.
2) Both subscriptions should be of the same type and amount: Parallels Desktop for Business cannot be extended with a Parallels Desktop Pro subscription just as a Parallels Desktop Pro for 2 computers can be extended with Parallels Desktop Pro for 2 computers only.
3) Neither subscription A nor B can be a promo key.
