Upgrade to Gmail -- Possible to restore mail?

I upgrade my emailing system to the gmail system. Does anyone know if its possible to transfer over the old email from squirrel mail or even get back on squirrel mail temporarily to look over some email?

If you have just changed, you may still be able to get onto your old email at DreamHost via SquirrelMail by going to webmail.dreamhost.com and entering your full email address and password.
