# 10.3. 从Spring Boot早期版本升级

如果你正在升级Spring Boot的早期发布版本，那最好查看下[project wiki](http://github.com/spring-projects/spring-boot/wiki)上的"迁移指南"，你会找到升级说明和一个对应每次版本发布的"new and noteworthy"特性列表。

想要升级一个已安装的CLI，你需要使用合适的包管理命令，例如`brew upgrade`；如果是手动安装CLI，按照[standard instructions](https://github.com/jack80342/spring-boot/tree/25350df33f8edd68b50ff6f6e1258c9df4f67d67/II.%20Getting%20Started/10.2.1.%20Manual%20installation.md)操作并记得更新你的PATH环境变量以移除任何老的引用。
