Hi!Yes, it's possible. You can purchase the upgrade.
Ans also let us know if you have any additional questions.
so I bought upgrade Parallels for home and unfortunately upgrade is not working with old key from old business. After use the new key and previous key parallels says:
The license server did not accept the previous activation key.
Check that you entered the key correctly. Your activation keys are stored in your Parallels account. If you do not want to bother with different activation keys and upgrade procedures in the future, we recommend that you purchase a Parallels Desktop subscription.
so... where is a problem, I am doing something wrong?
Thanks for reply.
