Using 2010 to bridge from 2003 to 2013

Hi there, I have one AD domain with exchange 2003 and would like to install both Exchange 2010 and 2013 on the network.

I know i can't directly migrate from 2003 to 2013, But wondered if I could take each mailbox in turn and move then to 2010, then from 2010 to 2013? We have less than 50 mailboxes.

the public folders would be saved as PST files and reconnected afterwards.

Then i'd decommission 2003 and 2010 to leave us with just 2013.

Is this possible?

Many thnaks
