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

Run database backup: pnpm migration:backup
Validate environment: pnpm migration:validate-env
Run pre-deployment checks: pnpm migration:pre-check

Migration

Run schema migrations: pnpm migration:schema
Run data migrations: pnpm migration:data
Deploy application: pnpm migration:deploy

Post-Migration

Validate deployment: pnpm migration:validate
Run health checks: pnpm migration:health-check
Test critical paths: pnpm migration:test

Rollback (if needed)

Rollback deployment: pnpm migration:rollback
Restore database: pnpm migration:restore

Environment Variables

The migration requires these new environment variables:

# 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:

Phase 1: Deploy new code with feature flags disabled
Phase 2: Run database migrations
Phase 3: Enable tRPC endpoints progressively
Phase 4: Enable batch processing system
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
