we have small network, which is DSLrouter-->ISA2000-->localnetwork-DC; Exchange 2003; Sharepoint.etc
I have read so many articles about this transision, but still i need some clerification on this issue. Even though our netowork users are less (25-30) and small network, our IT services are more critical. even we can not have one day down time, due the nature of business. that's why i want clear some point before begin the process.
We have already pruchased the server (DL380 G5) and installed the 64 bit windows 2003 (standard) with sp2, and patches. (Raid 5 configured)
now the questions.
1. will the exchange 2007 installation will distrub the current exchange 2003 .
2. what about the computer name for the new exchnge server befor join the domain
3. is it possible to run both the exchagne 2003 server and exchagne 2007 for some time for testing without affecting any user.
4. after transition can i bring back the same exchange 2003 server incase any problem couse in the 2007, to avoid the down time. until to find a solution for exchange 2007.
