Hi, I just did add a new windows 2003 R2 server (new hardware) to my Windows 2000 domain, in my domain I have just one windows 2000 DC, on this DC I run exchange 2000 as wel. After adding the new 2003 R2 server and promoting it to DC, I did move all the FSMO plus GC to new server. Now I want to install exchange 2003 on the new server (2003 R2) and add this exchange 2003 to my old exchange 2000 org, and after moveing every thing from Exc2000 to exc2003 decometion the 2000 DC. After I run deploy exchange 2003, I did choose the first exchange 2003 server option but after that I have some problem, which option should choose? do I have to choose coexsit with exchange 2000 and exchange 5.5? if I choose the coexsit with ex2000 and ex 5.5 do i have to go trouw with updating ADC as wel? Thanks, Shahin
