# 升级ExaGear for Server on Ubuntu

#### 升级前准备

1. 确保host系统已安装ExaGear for Server。
2. 将ExaGear for Server的所有配置文件拷贝至host系统目录备份：
  1 cp -r /opt/exagear/images/ubuntu-<os_version>-x86_64/.exagear/* /tmp


#### 升级步骤

1. 运行命令升级ExaGear for Server软件包。
  1 2 sudo dpkg -i exagear-utils_<package_version>_all.deb exagear-core-x64a64_<package_version>_arm64.deb exagear-core-x32a64_<package_version>_arm64.deb exagear-guest-for-ubuntu-<os_version>-x86_64-<package_version>_all.deb exagear-integration_<package_version>_all.deb sudo apt-get install -f

2. 将备份的ExaGear for Server配置文件与升级后的默认配置文件合并，以共享目录vpath-list配置文件为例，执行以下命令：
  1 cat /tmp/vpaths-list /opt/exagear/images/ubuntu-<os_version>-x86_64/.exagear/vpaths-list |sort|uniq > /opt/exagear/images/ubuntu-<os_version>-x86_64/.exagear/vpaths-list


#### 升级后检查

通过以下命令确认升级后的ExaGear for Server版本：

```
/opt/exagear/bin/ubt_x64a64_al -v
```

Revision与<package_version>一致则表示升级完成。

新版本ExaGear for Server将安装在旧版本上。所有guest系统中的Linux on x86应用程序及ExaGear for Server的相关配置均将保留
