Thanks for asking this question. The comment to your question by Gael pointed me in the right direction. I've just completed an upgrade of my legacy project. Here is how I did it:

1. 转到此链接: https://www.jhipster.tech/upgrading-an-application/
2. 按照自动升级的说明进行操作(在升级之前，请确保创建新分支，并确保存在合并冲突).
3. 解决合并冲突并运行测试.
4. 提交更改以避免重复工作.

在开始之前，请先全部阅读并理解说明，否则您会感到沮丧.

Above all read the instructions and understand them before beginning because otherwise you will become frustrated.
