推荐答案

Yii2 指南在这方面有很好的文档参见 从 v1 升级

The Yii2 guide has excellent documentation in this regard see Upgrade from v1

我最近将几个中等复杂的应用程序从 Yii 1.x 迁移到 Yii 2.0.有两种方法可以解决它，或者你可以同时运行 Yii 1.x 和 Yii 2 参见 使用-yii-2-with-yii-1.然后一点一点地迁移，虽然这可能会有点痛苦，就像住在三楼的时候试图重建二楼一样.

I recently migrated couple of moderately complex applications from Yii 1.x to Yii 2.0. There are two ways to go about it , either you can run Yii 1.x and Yii 2 at the same time see using-yii-2-with-yii-1. Then migrate part by part, while it is possible it was quite bit of pain, like trying to rebuild the second floor while living on the third.

或者，您可以使用完全相同的功能自下而上重写整个应用程序，我发现这样做效率更高，只需稍作修改即可重用重要代码，这也提供了在不更改功能的情况下调整设计的机会.

Alternatively you can rewrite the entire application bottom up with the exact same functionality, I found this to be much more efficient, significant code could be reused with only minor modifications, also that gave opportunity to tweak the design without changing functionality.

重要的是确保公开的 API(即前端/用户界面/功能)保持不变.在重写期间更新功能或更改特性总是很诱人，但是如果您坚持严格为 Yii2 重新实现所有内容，然后考虑更改您的 API，您的迁移将更加顺利.

The important thing is to ensure the exposed API ( i.e. the frontend / UI / functionality) remains the same. It is always tempting to update functionality or change features during a rewrite, however if you stick to strictly reimplementing everything for Yii2 then consider changing your API, your migration will be smoother.
