You should plan this ahead and make sure that your topic partition and replication factors are updated correctly using kafka topics admin or a batch job setup for Kafka Mirror Maker. Apache wiki explains how Mirror maker can guarantee a failsafe mirroring. I cannot quite remember how deep the mirroring goes e.g. Consumer offsets etc. But my understanding is that it should do it correctly.
