Compare and contrast the two machines for us.
It may be possible to just move the disks and reboot.

HOWEVER
Since this is a production environment that might
be reckless.

Make sure you have a "LiveCD" or "LiveUSBstick"
for the new machine so you can fix things.  

I would start with a fresh install and migrate
services and data, perhaps one service at a time.
Plan on multiple reinstalls and clone data and
config files with a script.

With the fresh install in place you can see a
lot that will help in the compare, contrast 
and planning process.

Install; clone data;test
Install; clone data;test
...
Install; clone data;test
Install; clone data;test
switch
