项目信息:
- 项目名称: MainWin
- 项目路径: $ProjectPath
- 当前IDE版本: Delphi 10.4/10.5 (推测)
- 目标IDE版本: Delphi 11 Alexandria (Version 28.0.48361.3236)

项目统计:
- 源代码文件: $((Get-ChildItem -Path "$ProjectPath\pas" -File).Count) 个
- 窗体文件: $((Get-ChildItem -Path "$ProjectPath\pas" -Filter "*.fmx").Count) 个
- 编译文件(DCU): $((Get-ChildItem -Path "$ProjectPath\dcu" -File -ErrorAction SilentlyContinue).Count) 个

依赖组件:
- FireDAC (内置)
- RESTComponents (内置)
- Indy (内置)
- EhLib (需要检查兼容性)
- SPComm (需要检查兼容性)
- TeeChart (需要检查兼容性)

升级步骤:
1. 在 Delphi 11 中打开 MainWin.dproj
2. IDE会自动提示升级项目
3. 点击 "Upgrade" 按钮
4. 重新安装第三方组件
5. 重新编译项目
6. 测试所有功能

注意事项:
- 升级前请完整备份项目
- 检查第三方组件是否支持 Delphi 11
- 可能需要更新部分代码
- 建议进行全面的功能测试
