Explanation
In this scenario, a PostgreSQL instance managed by NDB on a Linux VM is malfunctioning after a manual OS update, and a new Linux DB server VM has been prepared to host the data. To migrate the data to the new VM, the administrator must integrate the new VM into NDB's management framework. The correct action is to register the new DB Server VM in NDB, which allows NDB to recognize and manage the VM as a database server. Once registered, the administrator can use NDB's features (e.g., cloning, restoring, or reprovisioning) to migrate the data from the broken instance to the new VM.
