+
+   * Run the stop command and ensure the service has completely exited before 
performing subsequent operations.
+
+   ```shell
+   # Linux / MacOS
+   bash sbin/stop-ainode.sh

+   ```
+
+2. Replace core files
+
+   * Delete the `lib` and `sbin` directories of the current version, then copy 
the `lib` and `sbin` directories of the new version to the corresponding 
locations.
+   * Back up the modified configuration files in the `conf` directory, then 
replace the `conf` folder and synchronize the modified configurations to the 
corresponding locations.
+
+3. Update built-in model weights (optional)
+
+   * If the new version involves updates to built-in models, relevant 
information will be updated in the [Release 
History](../IoTDB-Introduction/Release-history_apache.md). You may contact 
Timecho staff to obtain the latest weight package and replace it in the 
`data/ainode/models/builtin` directory.

the node status. For specific commands, refer to Sections 3.4 and 3.5.

+
+1. Stop the current AINode service
+    - Run the stop command and ensure the service has completely exited before 
proceeding with subsequent operations.
+
+   ```bash
+   # Linux / MacOS
+   bash sbin/stop-ainode.sh
+   bash sbin/stop-ainode.sh -p <port_id> # Specify port
+   
+   # Windows
+   sbin\stop-ainode.bat  
+   sbin\stop-ainode.bat -p <port_id> # Specify port
+   ```
+
+2. Replace core files
+    - Delete the `lib` and `sbin` directories of the current version, then 
copy the `lib` and `sbin` directories from the new version to the corresponding 
locations.
+    - Back up the modified configuration files in the `conf` directory, then 
replace the `conf` folder and synchronize your modified configurations to the 
corresponding files.
+
+3. Update built-in model weights (optional)
+    - If the new version includes updates to built-in models, relevant 
information will be announced in the [Release 
History](../IoTDB-Introduction/Release-history_timecho.md). You may contact 
Timecho staff to obtain the latest weight package, and replace it in the 
`data/ainode/models/builtin` directory.

 AINode 是 IoTDB 在 ConfigNode、DataNode 后提供的第三种内生节点,该节点通过与 IoTDB 集群的 
DataNode、ConfigNode 交互,扩展了对时间序列进行机器学习分析的能力。AINode 
将模型的管理、训练及推理融合在数据库引擎中,支持使用注册的模型在指定时序数据上通过简单 SQL 
语句完成时序分析任务,还支持注册并使用自定义机器学习模型。AINode 目前已集成常见时序分析场景(例如预测)的机器学习算法和自研模型。
