Question : Move Mailbox from Exchange 2007 SP2 to Exchange 2010

Is it possible to move a mailbox/contacts for one user from Exchange 2007 SP2 to a different domain without a trust at different locations?  The target domain is running Exchange 2010?  The only option I have came up with is to export the Exchange 2007 users mailbox as a PST and re-import at the different site that is running Exchange 2010.  I was hoping for a simpler cleaner solution (such as copying the mailbox).  I have access to both domains and both exchange servers.  I am very limited in my knowledge of exchange server from the command line since I have always been lucky to get everything I need done via the GUI.  Any help would be appreciated.
