spec_r,

I'm not sure what kind of hardware you're currently running (make/model/RAM/processor/storage space, etc). Knowing this would help me provide more sound advice. While I DO believe that you could potentially roll both of your server's functions, apps, etc. onto a single SBS or S2K3 server - I'm thinking you be looking at a larger, faster server to handle all of that. I'm thinking a Quad Core Xeon server with 4-8GB RAM and a hardware RAID 5 disk array. In this case, I would also recommend that you go with S2K3 Enterprise and forget about SBS 2003. I say this because SBS2003 really limits you in terms of future expansion.

If you aren't able to invest in a high-end single-server solution and wish to keep your existing hardware (not sure what that is), I would break the environment up onto two servers - the SBS 2003 as the domain controller running Exchange, DHCP, Print & File Server - and put the remaining APPS on the second server running S2K3 - making it a member of the SBS2003 domain established from migrating over your old NTv4 domain environment.
