Upgrading from Outlook 2007 to 2013, old email history?

Any techy people know the best way to do the upgrade such that my old .pst Outlook 2007 email, contact and calendar history are integrated with the new stuff? I am not overlaying an old Outlook 2007, I bought a new computer and want to move the old history to the new computer with the newer Office 2013 program.

I tried this once and ended up with separate files, an old calendar and a new calendar, an old set of contacts and a new set, and old email history and a whole new set of email accounts. I did use Google to figure out how to put all the email addresses into a unified inbox, but is there a way to get the prior email history in that same display area?

Thanks!

Anybody?

You have to locate the .pst file and copy it over, have the new program load it, etc.

I did copy all the .pst files, but outlook 2013 using .ost files so while I could access the old stuff, it was in a whole separate mailbox/contacts/calendar, nothing was integrated on display. Is that really how they wrote it?

I wonder if I have to upgrade my old computer to 2013 and that would convert the files, then move it all?
