i taught i would post a couple of tools which are available to do this, unfortunately the function is not within exchange 2010 and you need third party tools… or you can put exchange 2007 in place first migrate to that and then to 2010 using the microsoft free tools (Microsoft Transporter Suite Download Here)




and of course




Personally, i would recommend trying going to exchange 2007 first as the other caveat you might not be aware of is that if for some reason you need something that was in exchange 2007 functionality but have gone straight to 2010 there is no way of bring a 2007 server in, so i would go the distance and go 2007 and then 2010..

but that’s my choice 🙂
