Will wordpress domain mapping upgrade redirect my RSS subscribers?

Hello!

I want to redirect traffic from my old wordpress.com site to my lovely new www.remarpro.com site. This seems possible with a domain mapping upgrade.

What the support page doesn’t specify, however, is whether the 34 Google Reader subscribers to the old blog will merge into the new feed (which currently only has 19 subscribers) with no action on their behalf. I’d love to consolidate these feeds so all 53 of my subscribers can be unified into one feed.

Does anyone know if the DM upgrade will have this effect automatically?

Suggestions of alternative ways of achieving this would also be hugely appreciated.

Thanks in advance.
