+## **1**. **系统安装**
+获取openEuler-22.03-LTS镜像，参考安装指南，完成openEuler操作系统的安装。
+
+查看当前环境openEuler、kernel版本
+
+![LTS_version](../images/22.03-LTS_22.03-LTS-SP1/LTS_version.png)
+
+
+## **2**. **升级兼容性**
+
+### 2.1 添加openEuler-22.03-LTS-SP1 repo源 (openEuler-22.03-LTS-SP1.repo)
+
+```
+SP1_OS、SP1_everything、SP1_EPOL、SP1_debuginfo、SP1_source、SP1_update 
+```
+
+![SP1_repo](../images/22.03-LTS_22.03-LTS-SP1/SP1_repo.png)
+
+
+### 2.2 获取openEuler-22.03-LTS-SP1中可安装的软件包名，并生成upgrade_list文件
+
+```
+dnf list --available --repo='SP1_OS' --repo='SP1_everything' --repo='SP1_EPOL' | grep "arch\|x86_64" | awk '{print $1}' | awk -F. 'OFS="."{$NF="";print}' | awk '{print substr($0, 1, length($0)-1)}'  > upgrade_list
+```
+
+### 2.3 执行升级
+
+```
+dnf install -y $(cat upgrade_list) | tee update_log
+```
+
+```
+补充说明：   
+1、安装报错时，通过执行 dnf install -y $(cat upgrade_list) --skip-broken -x conflict_pkg1 |tee update_log 规避安装冲突问题，如果有多个包冲突，添加多个-x conflict_pkg1 -x conflict_pkg2 -x conflict_pkg3，待升级完成后，对跳过的软件包单独进行分析、验证、升级
+
+2、22.03-LTS 到 22.03-LTS-SP1升级脚本如下：
+dnf install -y $(cat upgrade_list) --allowerasing --skip-broken -x ansible-2.9-2.9.24-3.oe2203sp1.noarch -x hadoop-3.1* -x redis5* -x redis6* -x ros-noetic-ros-nodelet_core -x python3-yarg -x protobuf-devel -x aops-web -x openvswitch -x protobuf-compiler -x LZMA-SDK -x libisal -x pin-server-demo -x kernel-rt-tools -x libtraceevent -x postgresql-server-devel -x dtkwidget-devel -x dtkwidget-devel -x libreswan -x nodejs-yarn -x python3-edk2-devel -x xorg-x11-server-help -x kiran-wallpapers -x mysql-config -x kata-containers  | tee update_log
+```
+
+### 2.4 重启系统
+
+```
+reboot
+```
+
+
+## **3**. **升级结果验证**
+
+查看当前环境的openEuler、kernel版本
+
+![SP1_version](../images/22.03-LTS_22.03-LTS-SP1/SP1_version.png)
+
+
+## **4**. **降级兼容性**
+
+### 4.1 执行降级
+
+```
+dnf downgrade -y $(cat upgrade_list) | tee downgrade_log
+```
+
+### 4.2 重启系统
+
+```
+reboot
+```
+
+## **5**. **降级结果验证**
+
+查看当前环境的openEuler、kernel版本
+
+![LTS_version](../images/22.03-LTS_22.03-LTS-SP1/LTS_version.png)
