Exchange in Trusted Domains

If I have 2 fully trusted domains each running Exchange servers, one 2003 and one 2007, is it possible to easily move mailboxes from one to the other?  If I can then will it cause any problems if I break the trust relationship afterwards?

What I'm doing is creating a new 'clean' domain and I want the easiest way to get my users moved into it, then I will abandon the old domain.

Yes, that's what the tool was designed for.  Rather than use a separate tool with older builds of Exchange, this version (2007) incorporates it.

The syntax is rather interesting, but I'm quite sure running it with a /? or /help should yeild the switches and syntax.

From the Exchange 2007 server you can use the command: Move-Mailbox.

I just want to confirm that using Move-Mailbox will allow me to move an Exchange 2003 mailbox in one domain to Exchange 2007 in another (trusted) domain?
