Then if you are using a load balancer, create a new VIP to gradually migrate your producers. (you should already have new datacenter members listed under new VIP.) Restarting one (producer) node at a time (after taking the server out of rotation) update the VIP to point to the new data center.</div>

<div>We are in process of migrating our services from one data center to another. We have a single instance RabbitMQ (version 2.3.1) (not clustered) running in current data center. We were able to migrate all our applications from 1 data center to another.
We want to migrate RabbitMQ (running 42 exchanges, 232 queues) to another data center with zero or little outage. I would like to ask the experts what steps we can carry to make sure that outage is minimal or zero.</div>
