1. An apparatus for wireless communication at a first integrated access and backhaul (IAB) donor central unit (CU), comprising:
one or more memories storing processor-executable code; and
one or more processors coupled with the one or more memories, at least one processor of the one or more processors configured to cause the apparatus to:
transmit, to a second IAB donor CU, context transfer information of a mobile termination (MT) of an IAB node;
transmit, to the second IAB donor CU, a resource configuration of a first cell served by the IAB node to initiate a migration of the IAB node from a distributed unit (DU) associated with the first IAB donor CU to a parent node serving a second cell associated with the second IAB donor CU, the resource configuration of the first cell including a DU cell resource configuration of the first cell, the DU cell resource configuration including at least one of a downlink, uplink and flexible (DUF) slot configuration or a hard, soft or not available (HSNA) slot configuration of the first cell, and the resource configuration of the first cell and the context transfer information being transmitted in separate messages, wherein one or more of the separate messages include an indication of an association between the resource configuration and the context transfer information;
receive, from the second IAB donor CU, an indication in accordance with the resource configuration; and
migrate the IAB node to the parent node serving the second cell according to the indication received from the second IAB donor CU.
