Master/slave replication does this out of the box, easily. Just set the slave to update on Optimize only. Then you can update the master as much as you want. When you are ready to update the slave (the search instance), just optimize the master. On the slave's next cycle check it will refresh itself, quickly, efficiently, minimal impact to search performance. No need to build extra moving parts for swapping search servers or anything like that.
