Exchange CCR cluster with 2003 transition

I am transitioning from a single Exchange 2003 server to a 2007 CCR cluster.  There is 1500 legacy mailboxes.  What happens when moving mailboxes from the legacy 2003 server to the new CCR Cluster.  Is the mailbox copied to both CCR stores at the same time?

There are no logs that deal with the data in the existing mailbox?

As per my understanding, one of the node is called Active and the other Passive. The current data/change will be processed only in the Active node and then the logs are shipped to passive node to replay the logs against the passive database.
