2003 to 2013 via 2010 question

I have built a 2010 SP3 server to move mailboxes from 2003. Ultimately, we are going to have a 2 node 2013 DAG and 2 front end servers. What I haven't been able to identify is if I can start building the 2013 with the 2003 still in production. I know 2013 does not coexist with 2003 but didn't know if I could at least install the servers.

Thanks
