From Exchange 2007 to Exchange 2013

Hi,

I'm currently looking to move from Exchange 2007 to 2013 on new hardware, I'm not really worry about them coexisting.

Can I disconnect Exchange 2007 from the internet move all the mail boxes over to 2013 and let outlook update the profile.

Just thinking this would be easier and quicker than setting them up to coexist.

Any thoughts are welcome :-)Thanks

Chris
