Server Migration Migrating a Management Node or Worker Node In the Admin Console, go to “Cluster Management” → “Replace Server” to migrate a Node. Replacement may interrupt related services, so a maintenance window is recommended. For detailed operations and restrictions, see “Node Management”. Migrating the Authorization Node Contact after-sales support to explain your migration needs and reasons, and submit the required approval materials. After approval, the original License will be invalidated, and after-sales support will provide a new activation code. Generate a fingerprint file for the new Authorization Node, then use the new activation code to create a License on the developer website. In the Admin Console, go to “License Management” → “Edit Authorization Node”, select the new Authorization Node, and import the new License.
