How to add a new 2012 DC to my current 2008 32bit DC's AD

I have 2 DC's running win 2008 32bit also Running DNS, DHCP with Domain Functional Level of Windows Server 2008.
I want to introduce a Windows Server 2012 as a DC and transfer the FSMO but I still want to keep running DNS and DHCP on th eolde 2008 32bit servers. ANY recommendation as of what steps should I take and should I also move DNS and DHCP to the new server?

install windows and all windows updates
then install the ADDS role and follow the wizard to promote to domain controller (no more adprep)
transfer fsmo roles

the 2008 server is still a domain controller running dns and dhcp
dns will be added to the 2012 server when you promote it; need to add that server for dns in your dhcp scope so clients can use it (and add manually to any statically configured devices)

you can migrate dhcp when you're ready

doesn't matter the architecture if your 2008 server is 32bit and 2012 is 64bit; will still work together as domain controllers
