How to merge subscriptions from two accounts into one?

Back in 2010 I subscribed to "Norton Internet Security", as it was called then, for my Windows NT system, and my account was associated with my email address myname@abc.org.

Years later, in 2017, I installed "Norton Password Manager" on my iPad, using another email address, myname@xyz.com.

Now I want to transfer my "Norton 360" subscription associated with myname@abc.org to my other account associated with myname@xyz.com, because I wish to discontinue my old email address.

Unfortunately my attempt to enter the "Norton 360" product key in my xyz.com account results in this message: "The product key you entered is associated with another Norton account".

Also I did not find a way do delete my xyz.com account so that I could then change the email address in my abc.org account to myname@xyz.com.

So is there a way to merge subscriptions from two accounts into one, or to transfer a product key from one account to another ?

TIA, Klaus.

Thanks for your recommendation, I will try to contact Norton support to have this issue resolved ...

To do this you need to contact Norton Support. They have access to your account to make changes like this.   www.norton.com/contactcs .

The only other thing you could do is wait until this subscription expires and then purchase a new product key that you can enter into the new email account you wish to use.
