[cisco-voip] CUCM Export

[Erick Wellnitz]

Do you have an extra MCS available?

I know it is a lot of steps but it would provide minimal disruption:  What
I would do is backup the current 6.1.3 and restore to the 'spare' MCS.
Upgrade on that to 8.0, backup and restore to VMWare. Upgrade to 9.1.
With all required penalty trips to licensing, of course.

All MACs would need to be done twice until you flip the switch on the DHCP
option 150 settings.  I might upgrade the phone firmware to match 9.1
before flipping the switch on option 150.  You can minimize downtime if you
use peer firmware sharing, provided you have phones that support it.

Maybe someone else has a simpler solution.
