+# main_db3 → main_db 마이그레이션 계획
+
+## 작성일: 2025-09-11
+## 목적: main_db3 데이터를 main_db로 통합
+
+---
+
+## 1. 현황 분석
+
+### main_db3 (삭제 예정)
+- 총 13개 테이블, 614개 레코드
+- 주요 데이터: users(17), companies(4), conversation_logs(555)
+- Slack/Gmail 연동 데이터 보유
+
+### main_db (운영 DB)
+- 총 11개 테이블, 대부분 비어있음
+- 기존 데이터: company(2), team(2)
+
+---
+
+## 2. 테이블 매핑
+
+| main_db3 | main_db | 비고 |
+|----------|---------|------|
+| companies | company | 2개 중복 확인 필요 |
+| users | user | team_id 필수 추가 |
+| workspaces | team | 구조 변환 필요 |
+| workspace_members | workspace_member | user_id 매핑 |
+| slack_workspaces | slack_workspace | team_id 매핑 |
+| user_preferences | user_preference | slack_user_id 제거됨 |
+| conversation_logs | conversation_log | robeing_id 컬럼 없음 |
+| gmail_tokens | gmail_token | 구조 동일 |
+| robeing_stats | robeing | product_id, team_id 추가 |
+| slack_user_mapping | - | workspace_member로 통합 |
+
+---
+
+## 3. 마이그레이션 순서
+
+### Phase 1: 조직 구조 (필수 선행)
+```sql
+-- 1. companies → company (중복 제외)
+INSERT INTO company (id, name, url, created_at, updated_at)
+SELECT id, name, domain, created_at, updated_at 
+FROM main_db3.companies 
+WHERE id NOT IN ('28f17b47-33f8-47ac-b1ae-100e77b37edb', '99d22d6b-d327-4fa4-bd2f-d228c11056e2');
+
+-- 2. workspaces → team 변환
+INSERT INTO team (id, company_id, name, created_at, updated_at)
+SELECT id, company_id, name, created_at, updated_at FROM main_db3.workspaces;
+```
+
+### Phase 2: 사용자 데이터
+```sql
+-- 3. users → user (기본 team_id 할당)
+INSERT INTO "user" (id, team_id, email, name, username, oauth_provider, oauth_id, is_active)
+SELECT u.id, 
+       COALESCE(wm.workspace_id, '38bdc27d-cb01-4960-867e-41733d2f3529'), -- 기본 팀
+       u.email, u.name, u.username, u.oauth_provider, u.oauth_id, u.is_active
+FROM main_db3.users u
+LEFT JOIN main_db3.workspace_members wm ON u.id = wm.user_id;
+
+-- 4. workspace_members → workspace_member (slack_user_id 추가 예정)
+INSERT INTO workspace_member (id, user_id, role, is_active, joined_at)
+SELECT id, user_id, role::user_role, is_active, joined_at FROM main_db3.workspace_members;
+```
+
+### Phase 3: 통합 데이터
+```sql
+-- 5. slack_workspaces → slack_workspace
+INSERT INTO slack_workspace (id, team_id, slack_team_id, bot_token, is_active)
+SELECT id, workspace_id, team_id, bot_token, is_active FROM main_db3.slack_workspaces;
+
+-- 6. user_preferences → user_preference (slack_user_id 제거)
+INSERT INTO user_preference (user_id, news_keywords, email_filter, briefing_enabled)
+SELECT user_id, news_keywords, email_filter, briefing_enabled FROM main_db3.user_preferences;
+
+-- 7. gmail_tokens → gmail_token
+INSERT INTO gmail_token SELECT * FROM main_db3.gmail_tokens;
+```
+
+### Phase 4: 대화 기록
+```sql
+-- 8. conversation_logs → conversation_log (컬럼 매핑 주의)
+INSERT INTO conversation_log (user_id, channel_id, message, response, intent, confidence, timestamp)
+SELECT user_id, channel_id, message, response, intent, confidence, timestamp 
+FROM main_db3.conversation_logs WHERE user_id IS NOT NULL;
+```
+
+---
+
+## 4. 검증 및 롤백
+
+### 검증
+- 레코드 수 대조
+- 외래키 무결성 확인
+- 주요 사용자 데이터 샘플 검증
+
+### 롤백 계획
+- 마이그레이션 전 main_db 백업
+- 실패 시 TRUNCATE 후 백업 복원
+
+---
+
+## 5. 주의사항
+- **team_id 필수**: user 테이블 INSERT 시 NOT NULL
+- **UUID 타입**: 모든 ID는 UUID 타입 유지
+- **slack_user_id**: workspace_member로 이동 예정
+- **실행 시간**: 새벽 시간대 권장 (서비스 영향 최소화)
