Hi all! we have a customer who are planning a move from Exchange 2007 to exchange 2010. We will install Exchange2010 cas/hub servers to start with. The old 2007 cas/Hub servers are currently suffering from bad performance. When we add the 2010 hub servers servers to the organisation, will they be utilized at all since all the mailboxes still resides on 2007? Best regards, UC

Hi and thanks for a fast answer! is there a way to offload the 2007 servers with the 2010 servers? For example outbound email or to route email to other sites?
