I have a Hotmail account which I'd like to copy all of the emails into a new Outlook account (not using aliases).  After copying them into the new Outlook account, I want to delete everything in the Hotmail account (but still keep it active).  Is there an automated way of doing this?  I have a very large number of emails (25,000+), so forwarding or individually copying is not going to work for me.  

If there is no automated way of doing this (using software), can I enlist Microsoft's paid support to do so?  Gotta get this done soon!!!

Thanks for whatever help anyone can provide!
