Archiving Exchange archived mails ?

Hi there,

can anybody answer me the following question:

One of our long-term EV customes, still using Exchange 2007, has acquired another company with an Exchange 2010 Server using Exchange archiving.

The question is now, if it is possible to use EV to archive these Exchange archived mails.

Technically, this should not be a problem, but I have no possibilities to test this (missing licenses). I am really sure, that if this is possible, EV creates another archive, because the Archiving Mailbox is technically another mailbox.
