The copy flash-synchro command will not work between different release versions of code.
Workaround: Both CMMs must have the same release version. If not, do the following:
1. Load each CMM separately with the new release in the "working" directory. When doing this, only
one CMM should be plugged into the chassis.
2. Perform reload working no roll-back on each CMM.
3. On each CMM, perform copy working certified.
4. Bring up the chassis with both CMMs.
5. Perform copy flash-synchro from the primary CMM.

In case of a takeover, cmmAUnPlugged and cmmBUnplugged alert traps are not sent on an OS7000 series
switch.
Workaround: There is no known workaround at this time.

Synchronization of flash fails if the elements are not running the same version of code.
Workaround: Only inserting the same version of software is supported. If this situation occurs, follow the
steps below to synchronize the flash to upgrade the stand alone unit to the same version before inserting:
1. Separate the elements of the stack to form two stacks; each running the same release version.
2. Upgrade one of the two stacks to the same release version as the other.
3. Reconnect the two stacks together to reform the initial stack.

Rarely, on takeovers, the "ipmem" task may crash. The switch must be rebooted to recover.
Workaround: There is no known workaround at this time.

On takeover, the NI LED momentarily displays amber.
Workaround: This is normal behavior indicating NI acknowledgement of takeover.

Changes made, but not saved on a redundant CMM setup, will not be reflected in the synchronization state
on an OS7000 series switch. The user may be unaware based on show running-directory that the NIs will
all reset on takeover.
Workaround: Changes in configuration should be saved and synchronized for redundant CMMs.
