Migrating from SBS 2008 to Server 2012 Stanard R2

I have a client currently running an SBS 2008 server on RAID 1. One of the drives in the RAID 1 failed and rather than replacing the drive, the client wants to buy a new server w/RAID 10 running Server 2012 Standard R2. The client is using the Exchange feature of SBS 2008, however, we will moving e-mail services to a hosted platform.

Question is: What is the best way to migrate from SBS 2008 to Server 2012? I have migrated from Server 2008 to Server 2012 without issues, but I have never done an SBS 2008 to Server 2012 migration. What else should I been on the look out for? Are there additional steps beyond the FSMO role, AD promotion/demotion, etc? Is there a guide for such a migration?

Thanks!

Short version:  Install DC role on 2012 R2; seize the FSMO roles from the SBS, migrate DNS/DHCP and then uninstall SBS 2008 from the server.  You will need original discs to uninstall the SBS from the server.  Make sure your client purchases the proper CALs for the new environment.

Thank you everyone for your quick and informative replies. My biggest concern was Exchange. From my past experience, what has been said here and what I have read elsewhere, I will migrate the client to hosted Exchange prior to taking any action on the SBS2008 server. Then, I will begin the process of best practices by uninstalling the Exchange feature, and moving forward from there.

Thanks again!
@RantCan - It will not be virtualized. Very small office of five 5 people.
Truly appreciate the information.
The size of the office is irrelevant for virtualization - you cannot replicate a non-virtual server for disaster recovery.  You are also throwing away a server license by not virtualizing - Server 2012 allows TWO VMs to run 2012 if you virtualize. If there ever comes a time when a new line of business app is needed that needs its own server or an RDS server is desired or an Exchange server, building your server TODAY as a VM will save LOTS of time and effort later.
