here is an excellent link which i found very useful


you will need to upgrade your exchange 5.5 server to 2000/2003 as you cannot install exchange 2007 if you still have a 5.5 server

your old server can remain on the network and you can use it as a file server no problem

first of all what you want to do is deploy a brand new server. install server 2003 64 bit.

now use adprep.exe /forestprep and /domainprep on the old 2000 server to prepare the schema for the new 2003 DC.

after premote the new 2003 server to a DC, use dcpromo and add it as an aditional DC within the forest.

set it as a Global catalog in sites and services and let it replicate. Also make sure it is a DNS server and has replicated the active directory intigrated DNS zones.

move all the 5 FSMO roles over to the new 2003 DC

move any thing else like DHCP etc over to the new DC.

demote the old 2000 server using DCpromo, or just leave it as a DC and also use it as a file server (this could be a good backup incase the 2003 fails one day)

now install exchange 2003 on a new server and use the ADC etc to migrate from 5.5 to 2003. see here: http://www.msexchange.org/tutorials/Migrating_Exchange_5_5_to_2003.html

you will then need to migrate from 2003 to 2007 using this method http://www.msexchange.org/tutorials/Transitioning-Exchange-2000-2003-Exchange-Server-2007-Part1.html

because you are on 5.5 and you want to g oall the way to 2007 you will have to do these 2 migration paths as 5.5 to 2007 is not possible.

 Thank you very much for the directions, it is exactly what I was hoping for ! Bert, I followed everything up to the 5 FMSO roles. Not a clue what those are. Also, the existing 2000 server is not set up properly as a DNS server. When I set the 2003 server as the DNS server will that take care of things?
I've got 2003 64 bit system installed and a member of the domain. When I run adprep.exe /forestprep and /domainprep do I run them from the 2000 server CD or the 2003 64 bit server cd? Or do I need a 2003 32 bit CD ?

Thanks both very much!

here is an easy way using the GUI to transfer all 5 roles: http://support.microsoft.com/kb/255690 follow that

is the 2000 DNS server an avtive directory intergrated? if so it should replicate to the 2003 server.
