What to do with the licence

Good day! Ive got Parallels Desktop 10 licence, and I would like to install 16 edition. What should I supposed to do - buy a new licence or simply upgrade old one?

 

Try it on Desktop 10 and if it doesn't work, you can click here to upgrade

 

Hello, you can purchase an upgrade version and activate it using your new Upgrade Parallels Desktop 16 key and your Parallels Desktop 10 license as a confirmation one.
Please let us know if you have any additional questions.

 

that worked great. thank you very much
