If the items below still feel unfamiliar, you usually get a better result by preparing first instead of rushing in.
Linux 发行版升级
OpenCloudOS 8/9 包管理
DNF/YUM
Linux 内核与软件包管理
系统兼容性测试
技术设计文档编写
The real friction is usually not library usage. It is validation, time allocation, and task framing.
难点不只是把软件包升级到 OC9，而是在不破坏既有业务配置和系统可用性的前提下处理内核、用户态包及不兼容配置；迁移后还要让网络、防火墙、SSH 和 http、mysql、ftp 等业务正常运行。作品需在提供的测试账户上可编译/运行或自带运行环境，增加了交付验证的工作量。
