Description

  • I have searched the issues of this repository and believe that this is not a duplicate.
  • I have checked the FAQ of this repository and believe that this is not a duplicate.

Environment

  • Dubbo version: <= 2.6.x
  • Operating System version: all
  • Java version: all

Steps to reproduce this issue

Dubbo 2.7.x 是1个跨度非常大的版本，该版本修改了包名、更新了许多依赖包。 这导致 旧版Dubbo 升级到 2.7.x 十分困难，稍有不当，就可能因为升级Dubbo而引发线上故障。 整个Dubbo社区普遍存在升级诉求，如果旧版本一直拖着不升级，容易形成长尾，影响Dubbo生态的发展。 因此，迫切需要为Dubbo升级提供更好的技术支持，建议：

  1. 梳理过往版本，确定1到多个LTS版本，如2.7.10、3.0，明确各版本的功能特性；
  2. 登记社区旧版本使用占比，整理出使用频率较高的版本，作为重点支持对象；
  3. 分析升级过程中的成本、风险、要点，整理成1套升级方法，作为最佳实践放到Wiki里；
  4. 基于最佳实践，开发升级辅助工具，自动检测冲突、更新代码甚至是一键升级。
