+# Migration Scripts for tRPC and Batch API Integration
+
+This directory contains comprehensive migration scripts for deploying the new architecture that includes tRPC implementation and OpenAI Batch API integration.
+
+## Migration Components
+
+### 1. Database Migrations
+- `01-schema-migrations.sql` - Prisma database schema migrations
+- `02-data-migrations.sql` - Data transformation scripts
+- `validate-database.ts` - Database validation and health checks
+
+### 2. Environment Configuration
+- `environment-migration.ts` - Environment variable migration guide
+- `config-validator.ts` - Configuration validation scripts
+
+### 3. Deployment Scripts
+- `deploy.ts` - Main deployment orchestrator
+- `pre-deployment-checks.ts` - Pre-deployment validation
+- `post-deployment-validation.ts` - Post-deployment verification
+- `rollback.ts` - Rollback procedures
+
+### 4. Health Checks
+- `health-checks.ts` - Comprehensive system health validation
+- `trpc-endpoint-tests.ts` - tRPC endpoint validation
+- `batch-processing-tests.ts` - Batch processing system tests
+
+### 5. Migration Utilities
+- `backup-database.ts` - Database backup procedures
+- `restore-database.ts` - Database restore procedures
+- `migration-logger.ts` - Migration logging utilities
+
+## Usage
+
+### Pre-Migration
+1. Run database backup: `pnpm migration:backup`
+2. Validate environment: `pnpm migration:validate-env`
+3. Run pre-deployment checks: `pnpm migration:pre-check`
+
+### Migration
+1. Run schema migrations: `pnpm migration:schema`
+2. Run data migrations: `pnpm migration:data`
+3. Deploy application: `pnpm migration:deploy`
+
+### Post-Migration
+1. Validate deployment: `pnpm migration:validate`
+2. Run health checks: `pnpm migration:health-check`
+3. Test critical paths: `pnpm migration:test`
+
+### Rollback (if needed)
+1. Rollback deployment: `pnpm migration:rollback`
+2. Restore database: `pnpm migration:restore`
+
+## Environment Variables
+
+The migration requires these new environment variables:
+
+```bash
+# tRPC Configuration
+TRPC_ENDPOINT_URL=http://localhost:3000/api/trpc
+TRPC_BATCH_TIMEOUT=30000
+
+# Batch Processing Configuration
+BATCH_PROCESSING_ENABLED=true
+BATCH_CREATE_INTERVAL="*/5 * * * *"
+BATCH_STATUS_CHECK_INTERVAL="*/2 * * * *"
+BATCH_RESULT_PROCESSING_INTERVAL="*/1 * * * *"
+BATCH_MAX_REQUESTS=1000
+BATCH_TIMEOUT_HOURS=24
+
+# Migration Specific
+MIGRATION_MODE=production
+MIGRATION_BACKUP_ENABLED=true
+MIGRATION_ROLLBACK_ENABLED=true
+```
+
+## Zero-Downtime Deployment Strategy
+
+The migration implements a blue-green deployment strategy:
+
+1. **Phase 1**: Deploy new code with feature flags disabled
+2. **Phase 2**: Run database migrations
+3. **Phase 3**: Enable tRPC endpoints progressively
+4. **Phase 4**: Enable batch processing system
+5. **Phase 5**: Full activation and old system decommission
+
+## Safety Features
+
+- Automatic database backups before migration
+- Rollback scripts for quick recovery
+- Health checks at each stage
+- Progressive feature enablement
+- Comprehensive logging and monitoring
+- Backwards compatibility maintained during migration
