I inherited this network and the previous network admin named this domain XYZ and then created a child domain UVW.XYZ. The exchange box is a member Server 2003 R2 SP2 (back-end) and Server 2003 R2 SP2 (Front End) in the DMZ, 5 DCs are server 2003 R2 SP2, 1 DC Server 2003 R2 SP1, 4 DCs Server 2008 STD SP2, the remaining 14 member servers are (12 Server 2003 R2 SP2 and 2 Server 2000 SP4).
Site 1: (2) Server 2003 R2 SP2 DCs, (1) Server 2003 R2 SP1 DC, (6) Server 2003 R2 SP2 Member Servers, own subnet
Site 2: (1) Server 2003 R2 SP2 DC, own subnet
Site 3: (1) Server R2 SP2 DC, (4) Server 2003 R2 SP2 Member Servers, own subnet
Site 4: (1) Server 2008 STD DC, own subnet
Site 5: (1) 2003 R2 SP2 DC and (1) Server 2008 STD DC, (1) Server 2003 R2 SP2 Member Sever, own subnet
Child Domain UVW.XYZ
On its own subnet

I want to rename the domain because i will be upgrading Exchange 2007 and once i do that i will not have the ability to rename it ever unless MS comes out with a fixup utility for 2007 or 2010. Plus i believe this would resolve a lot of issues i been having with replication and DNS.
Should i do the RENDOM or should i start a new Domain. If I start a new one can i run two domains on the same LAN? I do have enough servers to accommodate the second option but it seems like a lot of work.
Any suggestion would be great.
