following:
General Considerations
Components co-resident on servers
Multiphased upgrades are not supported in deployments with co-resident components.
CVP unit upgrades support co-resident components if all of the co-resident components
are part of the same unit. As with non-coresident components, the CVP unit must remain
offline until all components that comprise the unit are upgraded. For example, if you have
a co-resident VXML Server and Call Server in the same CVP unit, the unit can be upgraded;
when all of the components are upgraded the unit can begin to process calls.
ICM PG Combo
CVP/ICM PG combo deployment shares the SNMP infrastructure. The SNMP configuration
can be modified using either Contact Center SNMP or OAMP. OAMP maintains a private
view of the SNMP configuration file, and it is possible that there may be an overlap of
configuration parameters. If OAMP attempts to add a string that has already been configured
by the Contact Center SNMP, ORM returns an error.

handle calls, some call data may be lost. For example, if a 4.0 Reporting Server were to
