retiring 2011 sbs server

I have a customer with one clone server (SBS 2011). Email has been migrated to O365. It holds all the roles, DNS, DHCP, Print Management and shared applications. I will be setting up an new Windows 2012 server and need to migrate all to the new server, demote the existing and shut it down.

I have done this once with an SBS server and could not find a good "step by step" so I ended up chasing my tail quite a bit.

Anyone have a good article for this?

From my perspective, this is easy.  Simply add the 2012 server to the network and promote it to a DC.  Ensure all is well (DCDIAG tests), and then migrate your data and anything else you want to migrate.  When done, review the group policies and remove those that you won't be using anymore (such as the one for Windows Updates - don't have an SBS in front of me to tell you the exact policy name) and uninstall Exchange (to clean up AD) and then transfer the FSMO roles from SBS to the new 2012 server.  This will initiate the migration clock (21 days) before the SBS server starts shutting itself down.  Once the FSMO roles are migrated, demote the SBS server using DCPROMO and remove it from the network.

The key thing is you can have both servers as DCs on the network indefinitely.... UNTIL you transfer the FSMO roles.  That can easily be one of the last steps involved (and should be).
