Journalling on Mixed Mode Exchange 2003/2010

Hi

I have an exchange Mixed mode setup.  I want to decomission the 2003 server that has the Journaling mailbox on it, replacing it with an Exchange 2010 server.  The 2003 server does journalling for other Exchange 2003 servers.  Can we have exchange 2003 servers journaling to an Exchange 2010 server? 

If so, how?

Regards

Alison
