How can I transfer all subscribers from one feed to another from the same account?

[Proyecto Comunicativo]

I have created within my account two new blogs and feeds to complement the first blog. But I would like to transfer the subscribers to the two new feeds so they do not have to re-subscribe. Thank you.

Just update the Original Feed ?

Thank you, but I think I have not explained well. I need the two new feeds to have the same subscribers as the original since the two new blogs are part of the original. That is, to import the subscribers of the original to the two new ones.

Do all the Feedburner feeds have only rss/atom subscribers, only email subscribers, or both ? 

The list of email subscribers can only be exported, not imported - other than manually one 

address at a time - and each of them would still have to press the confirm link in their email 

like when they first subscribed.

I supposed. Thank you for solving my doubt.
