-Re: Can Observers be reconfigured in a DR situation?

Yes you can. Just edit the zoo.cfg from the backup DC, comment the lines
relative to the nodes in the primary DC and the observer peer type.
In this way you can start a new ZK ensemble with just the 3 servers on
But be aware that due to latency issues the backup DC could not have the
latest changes from the active DC.
You will also need to update each client "connection string" to use only
the servers from the backup DC.
