i have server 2003 pdc , and i want to upgrade my domain to 2008 mode.
i installed server 2008 32 bit in my network and promoted him to be a dc server (not a pdc yet, but after i will demote the 2003 pdc and my server 2008 will be the pdc).
i transferd all the fsmo rules to the new 2008 server , and now the next step is to take care of the schema by running addprep /domainprep /gpprep.
in my site im running also 4 “member dc’s” with 2008 64 bit.
i have 2 question about the situation:
1. is there any problem if my 2008(32 bit) pdc have to work with the others dc’s that are 64 bit?
2. if there is any problem if i have exchange 2007 that runs on server 2003 member server?
