Disclosed aspects relate to upgrade management for a shared pool of configurable computing resources having a set of logical partition (LPAR) nodes which includes a set of established members. Performance of a live kernel update (LKU) operation may be initiated with respect to a first original LPAR node. Generation of a first surrogate LPAR node to succeed the first original LPAR node may be initiated. The first surrogate LPAR node may be identified as a new original LPAR node. The first surrogate LPAR node may be joined with the set of LPAR nodes. In response to the first surrogate LPAR node joining the set of LPAR nodes, the first surrogate LPAR node may be identified as a new surrogate LPAR node. The first surrogate LPAR node may be established as a first established member, thereby removing the first original LPAR node from the set of established members.
