I don't think this is trivially fixed since you can still only have one writer that is holding the lease.
Your new service will come up, but it won't be able to get the write lease until the previous server shuts down. Now you have tools to detect this, stop one writer, and start the other, but the service will likely have to experience some kind of requests queueing or downtime.
