NOTE:
For Exchange 2007, in a consolidated role environment only the mailbox role is protected.
The Hub Transport and Client Access roles are not protected or failed over because they
are already installed on the target.
For Exchange 2007, replication and failover between a distributed role source
configuration to a consolidated role target configuration is permitted, provided that the
systems are configured as follows:
The source Mailbox Server role is installed on a standalone server or MSCS cluster
with the other roles residing on different servers.
The target configuration is a stand-alone server with the Mailbox, Hub Transport, and
Client Access roles installed.
In these configurations, Storage Mirroring will not replicate any data associated with the
Hub Transport/Client Access data; however, the target Hub Transport/Client Access roles
function properly when failing over the source Mailbox role, allowing necessary
operations to resume.
NOTE:
The Application Manager does not support configurations where Exchange and the
domain controller are on the same node of a cluster.
When using Exchange on a cluster, Exchange must be installed in its own uniquely named
group and not in the cluster group.
Like-named cluster support is only available for clusters running Exchange 2003. It is not
available for Exchange 2007.
