I am currently doing some work for a smal company of 70 users.
Currently the following exists:
Operating systems - Windows 2003 Server, 7 servers in total
2 x Domain controllers
1 file server
1 ISA 2006
1 Front End Exchange server (Exchange 2003)
1 Back End Exchange server (Exchange 2003)
1 Blackberry Server
All the servers listed above are on physical machines.
My first objective is to virtualiza the environment. Research indicates that it is recommended to use Exchange 2007 or 2010 instead of 2003.
So, I am considering migrating to Exchange 2010, and I have some questions:
I assume a Frent End server (or whatever the updated name of the role is) is still recommended. Is this assumption correct?
Is there any value to migrating the Front End server to Exchange 2010? Is it necessary? (I want to eliminate Exchange 2003 back end server and replace it with a virtual Exchange 2010). Since the orgianization is small, I do not forsee any issues upgrading to Exchange 2010.
Does anyone see any issues with leaving the Active Directory infrastructure using Windows 2003 servers in the scenario listed here? That is, all servers except for the Exchange 2010 will have 2003 (32 bit) as its operating system.
Another thing to note: OWA is used extensively,
Any comments / suggestions would be appreciated.
