Can't use older key when upgrading to Parallels 12

I'm trying to upgrade to 12 but apparently my previous version is too old.
Since I already bought the 12 upgrade, is it possible to just pay the difference to get the full license?
Thanks.
 
I have the same problem too! Had parallels 9 installed, bought the upgrade to 12 and my old activation key is not working. Is it possible to only pay the difference for the new key?
I have already sent an email to support but no reply yet.
Thanks.

Have the same issue: my most recent key was bought for v11 and now is an active PRO subscription. But then I'm asked for previous key, which when I provide (v10) and click [Activate], PD screen is loading sth, then stops and [Activate] button is active again. Nothing happens...
