+#### Special Note on DB-Migration Job Scheduling
+
+For the **db-migration job**, which applies database migrations at cluster startup, you can specify scheduling settings using the `task_*` configurations such as `task_node_selector`, `task_tolerations`, etc.  
+If these task-specific settings are not defined, the job will automatically use the global AWX configurations like `node_selector` and `tolerations`.
