If I reached all devices, may I change one of them?

Hello Jorge,
Thank you for contacting AVG Community Support.
We are really sorry to know this. We'll certainly check and help you out.
Yes, you could change. Ensure that AVG subscription is removed from your old device. If you don't have the old device to be active no issues. AVG counter will automatically check for active device count every 30 days and remove the unused device count thus paving way to use your subscription on new device. I hope you find it helpful. If you have any other queries, please feel free to contact us.
Thank you.

I have 10 devices suscription for multi-device, however, I think I'll be reach all of them soon. If I bought a new device, I'd prefer to install this suscription instead an old one, so, Could I change one device slot for that new one?
