Migration from Exchange 2007 to Exchange 2013

Perhaps someone has succeeded in doing this so I thought I would ask:)

We have an exchange 2007 server running on win 2008 R2. Many mailboxes.
The server has all roles, client access role, transport, mailbox.
We want to migrate over to One Exchange 2013 server, mailbox by mailbox if possible. Has anyone done this? any step-by-step lists on the web? the new server should co exist perhaps first as mailbox role - and mailflow goes thru the old or?

Appreciate any help,

I believe to do coexistance you have to wait for a Exchange 2007 update rollup to support Exchange 2013.  

Right now anyone on Exchange 2010 also has to wait for SP3 to add the capability.

ok thanks, will check that.

Does anyone know If we can move to 2010 instead - as our 2007 server is slow/full and we need to do something that works and fast?

That would be co-exist an internet facing Exchange 2007 server with all roles (single server) with a new single server Exchange 2010 server first being mailbox role server - i guess?

step by step would be the best:)

Exchange 2007 and 2010 can coexist.

I've never had to perform that so I'm sure there are others who could better assist.  Though there are guides online to give you some idea of requirements and such.  Below is a link to MS Exchange Deployment Assistant:

Though, if you wanted to jump right to 2013, you could use a tool like:

Probably wouldn't let you do it in a mailbox by mailbox model though.
