+# Gitea 迁移指南：Mac Studio → labmac3
+
+## 执行顺序
+
+1. `01_export_mac_studio.sh` — 在Mac Studio上导出Gitea数据
+2. 手动传输：`scp -r ~/gitea-backup duwenbo@192.168.1.77:/opt/`
+3. `02_setup_labmac3.sh` — 在labmac3上部署Gitea容器
+4. `03_restore_data.sh` — 恢复数据并验证
+5. `04_update_developer_remotes.sh` — 各开发者更新Git远程地址
+6. `05_create_repos.sh` — 创建3个仓库（ems-core, tp-ems, zpark-ems）
+
+## 注意事项
+- 所有SSH操作需要手动输入密码
+- 迁移前确保labmac3已安装Docker
+- 迁移完成后保留Mac Studio Gitea 1-2周作为备份
