Migrating sharepoint during sbs 2003 to sbs 2008 migration

Hi,

I went through the migration steps to move companyweb from my old sbs 2003 server to sbs 2008. Now per instructions, I have two intranet sites -- http://companyweb that goes to the default sharepoint server and http://oldcompanyweb that goes to the migrated site. That doesn't seem very useful. I want http://companyweb to contain the old data. How do I make that happen?

Thanks!
