8到10版本，功能点变动小，只是控制台页面变动比较大，但是11版本和上述版本的变动会很大，在10升级11和11降版本为10/9/8版本时，比如安装GITLAB时附加安装的“postgresql版本、初始化、表结构、字段、数据等兼容性”问题、核心配置文件“/etc/gitlab/gitlab.rb”的配置项改动和相关配置文件的配置问题、备份方式和一些命令改动等，这是几个比较大的变动。
个人推荐，不要在同一台机器上做11版本以下和11版本以上的版本升级和版本降级(需完全删除相关配置,记得提前备份)操作，更多版本变化需参考
“https://docs.gitlab.com/omnibus/update/gitlab_11_changes.html#114%20for%20details”
现有需求是从版本是8.14，升级到最新的11.9(这里只升级到10)，官方给出的标准是不要跨大版本升级，需要先从8升到9，从9升到10，最终从10升到11。其中升级的每个版本需要是每个版本的最终版本。下载的最终版本列表为:
