The following items are coexistence concerns that will affect how you plan your Office Communications Server 2007 R2 migration and deployment:
- Office Communications Server 2007 R2 Edge Servers cannot
communicate with internal Office Communications Server 2007
servers.
- Because the back-end database schema has changed with Office
Communications Server 2007 R2, you will need a new SQL Server
instance for each Office Communications Server 2007 R2 Enterprise
pool. An existing back-end server can host an Office Communications
Server 2007 R2 back-end database, but performance may be affected
if multiple databases are collocated.
- Outside Voice Control (Call Control Server or CCS) requires
Office Communications Server 2007 R2, Mediation Server.
- Office Communications Server 2007 R2, Monitoring Server, and
Office Communications Server 2007 R2, Archiving Server, will not
collect data from conversations that are hosted on Office
Communications Server 2007. Similarly, Office Communications Server
2007, QoE Monitoring Server, and Office Communications Server 2007,
Archiving and CDR Server, will not collect data from conversations
that are hosted on Office Communications Server 2007 R2. If you are
required to support QoE monitoring, archiving, and call data
recording, the existing QoE Monitoring Servers and Archiving and
CDR Servers must remain operational until the Office Communications
Server 2007 pools have been deprecated.
As noted previously, Office Communications Server 2007 R2,
Monitoring Server, will not collect data from traffic that is
hosted on Office Communications Server 2007; however, for
Enterprise Voice coexistence, Office Communications Server 2007,
Mediation Server, may need to be associated with the 2007 R2
release of the Monitoring Server. To do so, you must download and
run the script Associate.vbs on a machine that has the Office
Communications Server 2007 R2 snap-in. The script and usage
instructions are available for download from “Associate Office
Communication Server 2007 or Office Communication Server 2007 R2
Mediation Server with Office Communication Server 2007 R2 Pool” at
