| property | type | description |
|---|---|---|
| roleNamesToMigrate | array of roleNamesToMigrate (string) | The list of role names to migrate. |
| destinationHostId | destinationHostId (string) | The ID of the host to which the roles should be migrated. |
| clearStaleRoleData | clearStaleRoleData (boolean) | Delete existing stale role data, if any. For example, when migrating a NameNode, if the destination host has stale data in the NameNode data directories (possibly because a NameNode role was previously located there), this stale data will be deleted before migrating the role. |
