We have Exchage 2003 SP2
Two AD Forest

Forest A  (1900 Users) -    Have Blackberry, iPhones, OWA and Outlook 2003 and Outlook 2007
2 Inbound Gateways (Symantec SMTP)
2 Front End Servers
4 BackEnd Servers including 1 BE that is a Notes Connector
1 Internal Outbound Relay Server (Symantc SMTP GW)

Forest B  (Small 500 Users)
1 - FE
1- BE

Looking to find a drawing of what a Exchange 2007 Environment would look like to migrate to .
Wondering what servers wold be needed on the Back end to Migrate over to .
I know that the servers have to be 64bit  ......   I know we would initially have to have it integrated with our current environment. and then get everyone on Exchange 2007.  

Looking for a basic Design for Budget Purposes  - Trying to see a number of equipment needed so I can put a Swag in for the Budget for next year .  

Need something by tomorrow !   Yipee !!

Thanks,
David

Below is a "Budget" design based on the info provided.

Forest A

  1. Will Still Need a 2003 Notes Connector Server if this interaction is still needed
  2. If you are using your Symantec Devices as SMTP Gateways, there is no need for Edge Servers
  3. As such, 1x Servers combining the HUB and CAS roles (2 would obviously give resilience)
  4. 2x mailbox servers to host the mailboxes (Could be more dependent dependent on Spec of hardware)
Forest B
  1. 1 Server Handling HUB/CAS Roles
  2. 1 Server Handling Mailbox Roles
  3. I'm assuming all internal and external mail flows via Forest A, as such no Edge Server is required here.

What do you mean by give more resilience ... in #3 above ? ?

For my 2000 mailboxes you would only have 2 mailbox servers ?
