I have 3 servers in a single CM cluster. The second Subscriber is on a different site. In event of a DR scenario, and the primary site being lost(destroyed), I am left with a single Subscriber to continue call processing.

However, in this scenario, I would likely need to make some configuration changes (such as configuring new users, creating translation patterns - maybe changing pickup groups / hunt lists) and I believe this wont be possible with only a Subscriber active.

Is there a way that a Subscriber could be converted into a Publisher to facilitate these changes ? In this event, the original Publisher would be destroyed and would eventually be re-installed on new hardware (as a subscriber if necessary). So this isn't a role change I would look to flick back and forth - it would be a permanent change.

I would like to have this option documented - rather than rely solely on getting new hardware a rebuilding the Publisher from scratch before admin changes could be made, should this situation arise.
