So, i suggest to update from version 5 to version 6 in this way:
1. You don't touch old `next` dir and just do some copies of NexT files:\
- 1.1. `config.yml` or `next.yml` (if you used [data-files](DATA-FILES.md)).\
+ 1.1. `_config.yml` or `next.yml` (if you used [data-files](DATA-FILES.md)).\
1.2. Custom CSS styles what placed in `next/source/css/_custom/*` and `next/source/css/_variables/*` directories.\
1.3. Custom layout styles what placed in `next/layout/_custom/*`.\
1.4. Any another possible custom additions which can be finded by compare tools between repos.
2. Clone new v6.x repo to any another directory instead of `next`. For example, in `next-reloaded` directory: `git clone https://github.com/theme-next/hexo-theme-next themes/next-reloaded`. So, you don't touch your old NexT 5.1.x directory and can work with new `next-reloaded` dir.
3. Go to Hexo main config and set theme parameter: `theme: next-reloaded`. So, your `next-reloaded` directory must loading with your generation. If you may see any bugs or you simply not like this version, you anytime can switch for 5.1.x version back.
+4. Update language configuration (For Chinese)
+
+ Since v6.0.3, `zh-Hans` has been renamed to `zh-CN`: https://github.com/theme-next/hexo-theme-next/releases/tag/v6.0.3
+
+ Users upgrading to v6.0.3 and later need to explicitly modify the `language` configuration in the Hexo main config file `_config.yml`, otherwise the language display is incorrect.
And how to enable 3rd-party libraries see [here](https://github.com/theme-next/hexo-theme-next/blob/master/docs/INSTALLATION.md#plugins).

推荐通过如下步骤从 v5 升级到 v6:
1. 并不修改原有的 `next` 目录,而只是复制部分 NexT 文件:
- 1. `config.yml` 或 `next.yml`(如果你使用了[数据文件](DATA-FILES.md))。
+ 1. `_config.yml` 或 `next.yml`(如果你使用了[数据文件](DATA-FILES.md))。
2. 自定义的 CSS 配置,它们应在 `next/source/css/_custom/*` 和 `next/source/css/_variables/*` 中。
3. 自定义的排布配置,它们应在 `next/layout/_custom/*` 中。
4. 任何其它可能的附加自定义内容;为了定位它们,你可以通过某些工具在仓库间比较。
