Technologies for switching a set of nodes in an overlay network from one relay tree configuration to another without duplicate packets or packet loss at any of the nodes. A commander node calculates a new relay tree as well as a media stream set configuration for each node in the overlay network, each media stream set corresponding to the new relay tree. Media stream sets include a unique version number or the like that identifies the specific relay tree configuration of which they are a part. Also provided are technologies for associating a media stream with a particular relay tree configuration and the corresponding media stream set of each node in the overlay network.
