Abstract: A storage system and method for performing upgrade management are provided. A plurality of nodes in the storage systems are divided into groups. A scheduling node obtains a constraint condition of each group. The constraint condition comprises a maximum quantity of nodes in a corresponding group that are allowed to be upgraded in parallel. Nodes in a first batch for upgrading in parallel from the groups based on the constraint condition of each group are selected. An upgrade instruction is sent to the nodes in the first batch.
