【问题描述】：

我想将我的 Laravel 项目从（5.5 升级到 8）我将为此做些什么。我没有找到任何从 5.5 升级到 8 的文件，只是从 5.5 升级到 5.6 或从 7 升级到 8 可能必须逐步将项目从 5.5 升级到 5.6，然后从 5.6 升级到 5.7 然后.... nutil 8 谢谢

【解决方案1】：

看起来升级是按顺序进行的。截至今天，我有一个 laravel 5.7 项目，我必须升级到 Laravel 8，这看起来像是我需要采取的顺序。

即使您选择了强烈推荐的 Laravel Shift，您也必须为每次升级付费，如下图所示。

如果您有预算，laravel shift 看起来是一种快速简便的升级方式

【解决方案2】：

恐怕你将不得不迭代升级。

如果你有预算，你可以使用 Laravel Shift 之类的服务自动升级。

【讨论】：

感谢您指出 Laravel Shift，它节省了大量升级时间。从 5.5 更新到 8.x 只用了大约一周时间，大部分时间都花在了 laravel excel 的重写函数上。
