psunith -> 4 Node DAG & FSW - Queries (31.Dec.2014 8:14:28 AM)

We are migrating from Exchange 2007 to Exchange 2013.

Exchange 2007 is a single box with all roles in one.

OS Windows Server 2008 Enterprise Version 6.0 (Build 6002) Service Pack 2

Exchange Microsoft Exchange Server 2007 Version

All Mailbox servers on Exchange 2013 below are on

Windows Server 2012 R2 Standard Build 9600
Microsoft Exchange Server 2013 Service Pack 1 Version 15.0.847.32
Our setup for Exchange 2013 is 4 mailbox servers and 1 CAS.

EXMB01 DB1 (Active) DB2 (Passive)
EXMB02 DB2(Active) DB3 (Passive)
EXMB03 DB3 (Active) DB1 (Passive)
EXMB04 DB 1, DB2 & DB3 (All Passive) The main reason for this mailbox server is for running mailbox and db backups to ensure the other servers do not get loaded.
My questions are:

How do I setup a DAG in this setup.
How many DAG groups must I have?
I have a non-exchange machine setup as FSW. Kindly advise how I need to configure this?
For coexistence between Exchange 2007 and Exchange 2013, kindly advise the minimum versions and/or service packs required.
Appreciate your help in this to ensure the migration is smooth.
