A plurality of communications nodes are configured to form a wireless backhaul network to communicate data from a core network of the wireless communications network for transmitting to one or more communications devices or to communicate data to the core network received from the one or more communications devices. At least a first and a second of the plurality of communications nodes are donor communications nodes formed from radio network infrastructure equipment having a physical connection to the core network. According to example embodiments, a migrating communications node determines that it should migrate from a first attachment point in the wireless backhaul network in which the migrating node communicates the data to or from the core network via the first donor communications node. The term 'attachment point' is used to express a link of a communications node to other nodes in the backhaul network. The radio communications links are formed to communicate data to and from the core network via donor communications nodes and may be also via one or other nodes according to an established hierarchy of the wireless backhaul network. The migrating communications node determines a second attachment point in the wireless backhaul network to which the migrating communications node should attach to the wireless backhaul network to communicate the data to or from the core network, and the migrating communications node migrates from the first attachment point to the second attachment point. The second attachment point is determined by biasing a selection of the second attachment point either to provide the migrating communications node with radio communications resources from the first donor communications nodes when attached to the wireless backhaul network at the second attachment point as an intra-donor migration, or to provide the migrating communications node with radio communications resources from the second donor communications node when attached to the wireless backhaul network at the second attachment point as an inter-donor migration.
