Changing my existing Bitdefender accounts to my Netgear Armor account

I recently extended my Netgear Armor coverage and noted that it now includes Bitdefender for my other devices.  I already have Bitdefender installed on those other devices.

Do I have to reinstall Bitdefender on those other devices in order to be under the Armor account?

How do I transfer my existing Bitdefender accounts to the coverage under Armor?

Is there any credit that can be given for the remaining time on my current Bitdefender accounts?
