# Complete Migration Automation Guide
**Date**: 2025-01-27
**Purpose**: Complete guide for automated project migrations
**Status**: Complete
---
## Overview
This guide provides complete automation for migrating projects to shared infrastructure, monorepos, and services.
---
## DBIS Monorepo Migration
### Automated Migration
#### Single Project
```bash
./scripts/dbis/automate-dbis-migration.sh dbis_core dbis_monorepo packages
```
**What it does**:
- Copies project to monorepo
- Updates package.json name
- Creates migration notes
- Provides next steps
#### All Projects
```bash
./scripts/dbis/migrate-all-dbis-projects.sh dbis_monorepo
```
**What it does**:
- Migrates all DBIS projects
- Creates migration notes for each
- Provides comprehensive next steps
### Manual Steps After Automation
1. **Update Dependencies**
```bash
cd dbis_monorepo/packages/dbis_core
# Edit package.json to use @dbis/* and @workspace/* packages
```
2. **Update Imports**
```typescript
// Before
import { User } from '../types';
// After
import { User } from '@dbis/shared-types';
```
3. **Test Build**
```bash
cd dbis_monorepo
pnpm install
pnpm build
```
4. **Test Tests**
```bash
pnpm test
```

## Infrastructure Migrations
### Monitoring Migration
```bash
./scripts/migration/migrate-to-monitoring.sh my-project production
```
### Kubernetes Migration
```bash
./scripts/migration/migrate-to-k8s.sh my-project
```
### API Gateway Migration
```bash
./scripts/migration/migrate-to-api-gateway.sh my-service http://my-service:8080
```
### Shared Packages Migration
```bash
./scripts/migration/migrate-to-shared-packages.sh
```
### Terraform Migration
```bash
./scripts/migration/migrate-terraform.sh
```

## Migration Workflow
### Pre-Migration
1. Review migration guide
2. Backup current state
3. Set up test environment
4. Review dependencies
### Migration
1. Run automation script
2. Review generated files
3. Update configurations
4. Test in isolation
### Post-Migration
1. Verify functionality
2. Update documentation
3. Deploy to staging
4. Monitor metrics
5. Deploy to production

## Verification Checklist
### After Each Migration
- [ ] Build successful
- [ ] Tests passing
- [ ] Dependencies resolved
- [ ] Imports updated
- [ ] Configuration correct
- [ ] Documentation updated
### Before Production
- [ ] Staging deployment successful
- [ ] Integration tests passing
- [ ] Performance acceptable
- [ ] Monitoring configured
- [ ] Rollback plan ready
---
## Troubleshooting
### Common Issues
#### Build Failures
- Check dependencies
- Verify TypeScript configuration
- Review import paths
- Check for missing files
#### Test Failures
- Update test configurations
- Fix import paths
- Update mocks
- Review test data
#### Dependency Issues
- Verify workspace protocol
- Check package versions
- Review peer dependencies
