I am in the planning stage of upgrading 3 sql servers a Citrix server and the PDC to windows 2008. Must I upgrade the PDC first or will a Windows 2003 Server OS running on the PDC work ok with upgraded Citrix server and SQL servers? The reason I ask is because the hardware that the PDC is running on is not up to Windows 2008 required specs. However the other server are up to the required specs.It Support Assistnat
