7.0 DMM Exceptions or Limitations
In many cases DMM will be able to effect a 100% migration of data from the source to the target. However,
there are some identified configurations for which DMM can not migrate 100% of the data from source to target.
For each DMM supported source/target migration path this section describes any limitations or configuration
issues that may prevent DMM from achieving a 100% migration result.
It is recommended that Appendix A – System Compatibility be consulted to ensure that all source/target
compatibility requirements have been met and understood before attempting to use DMM.
7.1 BCM 4.0 (200/400) to BCM 5.0 (450 chassis)
7.1.1 IP Sets Must be Re-registered to DNs on the Target
DMM migration to BCM5.0 will transfer the IP DNs and their programming, but the registration of the physical
IP Sets to their respective DNs will need to be performed as a post-DMM step.
7.1.2 Line Numbers on CTM8/GATM8/8x16 MBMs Will Change
On the target BCM5.0 system there will not be a 4 line gap in the line numbering between the first set of 4 lines
and the second set of 4 lines on an 8 line MBM. The second set of 4 lines on the MBM will be numbered
contiguously from the first set of 4 lines.
This means that the second set of 4 lines on every 8 line MBM will have different line numbers on the target as
compared to the original source system.
7.1.3 Some Programming Migration May Fail if “Hardware-Less” DNs are Referenced
On a BCM4.0 source DNs that reside on a bus for which a “Stn Mod” is not the “Prog Type” will not be re-
created on a target BCM5.0 system. As a result, if on the source BCM4.0 system there were such DNs
referenced in programming (e.g., as prime set, control set, direct dial set, etc.) then the attempt to migrate that
programming onto the BCM5.0 system will fail because those DNs will not exist on the BCM5.0 system.
7.1.4 Call Forward All Calls Programming Not Migrated
If a DN on the source system is programmed to Call Forward All Calls to another destination this programming
will not be migrated to the target system. This configuration must be performed manually post-DMM migration.
7.1.5 Doorphone Programming Not Migrated
No Doorphone programming of any type will be migrated from the source to the target. This configuration must
be performed manually post-DMM migration.
7.1.6 Internal CAP Assignment Not Migrated
DMM will not currently migrate CAP / DN assignments. This programming must be performed manually post-
DMM migration.
