+# Tenant Migration Guide
+
+## Quick Start
+
+### Create a New Migration
+```bash
+cd backend
+npm run migrate:make add_your_feature_name
+```
+
+Edit the generated file in `backend/migrations/tenant/`
+
+### Test on Single Tenant
+```bash
+npm run migrate:tenant acme-corp
+```
+
+### Apply to All Tenants
+```bash
+npm run migrate:all-tenants
+```
+
+## Available Commands
+
+| Command | Description |
+|---------|-------------|
+| `npm run migrate:make <name>` | Create a new migration file |
+| `npm run migrate:tenant <slug>` | Run migrations for a specific tenant |
+| `npm run migrate:all-tenants` | Run migrations for all active tenants |
+| `npm run migrate:latest` | Run migrations (default DB - rarely used) |
+| `npm run migrate:rollback` | Rollback last migration (default DB) |

+```
+
+### How Migrations Work
+
+1. **New Tenant Provisioning** (Automatic)
+   - User creates tenant via API
+   - `TenantProvisioningService.provisionTenant()` is called
+   - Database is created
+   - All migrations in `migrations/tenant/` are automatically run
+   - Tenant status set to ACTIVE
+
+2. **Existing Tenants** (Manual)
+   - Developer creates new migration file
+   - Tests on single tenant: `npm run migrate:tenant test-tenant`
+   - Applies to all: `npm run migrate:all-tenants`
+   - Each tenant database is updated independently
+
+### Migration Scripts
+
+#### `migrate-tenant.ts`
+- Accepts tenant slug or ID as argument
+- Fetches tenant from central database
+- Decrypts database password
+- Creates Knex connection to tenant DB
+- Runs pending migrations
+- Reports success/failure
+
+#### `migrate-all-tenants.ts`
+- Fetches all ACTIVE tenants from central DB
+- Iterates through each tenant
+- Runs migrations sequentially
+- Collects success/failure results
+- Provides comprehensive summary
+- Exits with error if any tenant fails
+
+## Security
+
+### Password Encryption
+
+Tenant database passwords are encrypted using **AES-256-CBC** and stored in the central database.
+
+**Required Environment Variable:**
+```bash
+DB_ENCRYPTION_KEY=your-32-character-secret-key!!
+```
+
+This key must:
+- Be exactly 32 characters (256 bits)
+- Match the key used by backend services
+- Be kept secure (never commit to git)
+- Be the same across all environments accessing tenant DBs
+
+### Encryption Flow
+
+```
+Tenant Creation:
+  Plain Password → Encrypt → Store in Central DB
+
+Migration Time:
+  Encrypted Password → Decrypt → Connect to Tenant DB → Run Migrations
+```
+
+## Example Workflow
+
+### Adding a New Field to All Tenants
+
+```bash
+# 1. Create migration
+cd backend
+npm run migrate:make add_priority_to_tasks
+
+# 2. Edit the migration file
+# migrations/tenant/20250127120000_add_priority_to_tasks.js
+
+# 3. Test on staging tenant
+npm run migrate:tenant staging-company
+
+# 4. Verify it worked
+# Connect to staging DB and check schema
+
+# 5. Apply to all tenants
+npm run migrate:all-tenants
+```
+
+Expected output:
+```
+🚀 Starting migration for all tenants...
+
+📋 Found 5 active tenant(s)
+
+🔄 Migrating tenant: Acme Corp (acme_corp_db)
+✅ Acme Corp: Ran 1 migrations:
+   - 20250127120000_add_priority_to_tasks.js
+
+🔄 Migrating tenant: TechStart (techstart_db)
+✅ TechStart: Ran 1 migrations:
+   - 20250127120000_add_priority_to_tasks.js
+
+...
+
+============================================================
+📊 Migration Summary
+============================================================
+✅ Successful: 5
+❌ Failed: 0
+
+🎉 All tenant migrations completed successfully!
+```
+
+## Troubleshooting
+
+### Error: "Cannot find module '../prisma/generated-central/client'"
+
+**Solution:** Generate Prisma client
+```bash
+cd backend
+npx prisma generate --schema=prisma/schema-central.prisma
+```
+
+### Error: "Invalid encrypted password format"
+
+**Solution:** Check `DB_ENCRYPTION_KEY` environment variable matches the one used for encryption.
+
+### Error: "Migration failed: Table already exists"
+
+**Cause:** Migration was partially applied or run manually
+
+**Solution:**
+```bash
+# Check migration status in tenant DB
+mysql -h <host> -u <user> -p<pass> <dbname> -e "SELECT * FROM knex_migrations"
+
+# If migration is listed, it's already applied
+# If not, investigate why table exists and fix manually
+```
+
+### Migration Hangs
+
+**Possible causes:**
+- Network connection to database lost
+- Database server down
+- Migration has long-running query
+
+**Solution:** Add timeout to migration and check database connectivity
+
+## Best Practices
+
+1. ✅ **Test first**: Always test migrations on a single tenant before applying to all
+2. ✅ **Rollback ready**: Write `down()` functions for every migration
+3. ✅ **Idempotent**: Use `IF NOT EXISTS` clauses where possible
+4. ✅ **Backup**: Take database backups before major migrations
+5. ✅ **Monitor**: Watch the output of `migrate:all-tenants` carefully
+6. ✅ **Version control**: Commit migration files to git
+7. ✅ **Document**: Add comments explaining complex migrations
+
+8. ❌ **Don't skip testing**: Never run untested migrations on production
+9. ❌ **Don't modify**: Never modify existing migration files after they're deployed
+10. ❌ **Don't forget down()**: Always implement rollback logic
+
+## Integration with TenantProvisioningService
+
+The migrations are also used during tenant provisioning:
+
+```typescript
+// src/tenant/tenant-provisioning.service.ts
+
+async provisionTenant(tenantId: string): Promise<void> {
+  // ... create database ...
+  
+  // Run migrations automatically
+  await this.runTenantMigrations(tenant);
+  
+  // ... update tenant status ...
+}
+
+async runTenantMigrations(tenant: any): Promise<void> {
+  const knexConfig = {
+    client: 'mysql2',
+    connection: {
+      host: tenant.dbHost,
+      port: tenant.dbPort,
+      user: tenant.dbUser,
+      password: decryptedPassword,
+      database: tenant.dbName,
+    },
+    migrations: {
+      directory: './migrations/tenant',
+    },
+  };
+
+  const knexInstance = knex(knexConfig);
+  await knexInstance.migrate.latest();
+  await knexInstance.destroy();
+}
+```
+
+This ensures every new tenant starts with the complete schema.
+
+## CI/CD Integration
+
+### Docker Compose
+```yaml
+services:
+  backend:
+    image: your-backend:latest
+    command: sh -c "npm run migrate:all-tenants && npm run start:prod"
+    environment:
+      - DB_ENCRYPTION_KEY=${DB_ENCRYPTION_KEY}
+```
+
+### Kubernetes Job
+```yaml

+
+### Migration Flow
+
+1. **Creating a Migration**
+   ```bash
+   npm run migrate:make add_custom_fields
+   # Creates: migrations/tenant/20250127123456_add_custom_fields.js
+   ```
+
+2. **Testing on Single Tenant**
+   ```bash
+   npm run migrate:tenant acme-corp
+   # Output:
+   # 📋 Tenant: Acme Corp (acme-corp)
+   # 📊 Database: acme_corp_db
+   # 🔄 Running migrations...
+   # ✅ Ran 1 migration(s):
+   #    - 20250127123456_add_custom_fields.js
+   ```
+
+3. **Checking Status**
+   ```bash
+   npm run migrate:status
+   # Shows which tenants have pending migrations
+   ```
+
+4. **Applying to All Tenants**
+   ```bash
+   npm run migrate:all-tenants
+   # Migrates all active tenants sequentially
+   # Provides summary of successes/failures
+   ```
+
+## 🔐 Security Features
+
+### Password Encryption
+- Tenant database passwords are encrypted using **AES-256-CBC**
+- Stored encrypted in central database
+- Automatically decrypted during migration
+- Requires `DB_ENCRYPTION_KEY` environment variable
+
+### Environment Setup
+```bash
+# Required for migration scripts
+export DB_ENCRYPTION_KEY="your-32-character-secret-key!!"
+```
+
+This key must match the key used by `TenantService` for encryption/decryption.
+
+## 📋 Example Workflows
+
+### Scenario 1: Adding a Field to All Tenants
+
+```bash
+# 1. Create migration
+npm run migrate:make add_priority_field
+
+# 2. Edit the generated file
+# migrations/tenant/20250127120000_add_priority_field.js
+
+# 3. Test on one tenant
+npm run migrate:tenant test-company
+
+# 4. Check status
+npm run migrate:status
+
+# 5. Apply to all
+npm run migrate:all-tenants
+```
+
+### Scenario 2: Checking Migration Status
+
+```bash
+npm run migrate:status
+
+# Output:
+# 📋 Found 3 active tenant(s)
+# 
+# 📦 Acme Corp (acme-corp)
+#    Database: acme_corp_db
+#    Completed: 5 migration(s)
+#    ✅ Up to date
+#
+# 📦 TechStart (techstart)
+#    Database: techstart_db
+#    Completed: 4 migration(s)
+#    ⚠️  Pending: 1 migration(s)
+#       - 20250127120000_add_priority_field.js
+#
+# 💡 Run: npm run migrate:all-tenants
+```
+
+### Scenario 3: New Tenant Provisioning (Automatic)
+
+When a new tenant is created via the API:
+```typescript
+// Happens automatically in TenantProvisioningService
+POST /tenants
+{
+  "name": "New Company",
+  "slug": "new-company"
+}
+
+// Backend automatically:
+// 1. Creates database
+// 2. Runs all migrations
+// 3. Sets tenant status to ACTIVE
+```
+
+## 🛠️ Technical Implementation
+
+### Script Structure
+
+All scripts follow this pattern:
+
+1. **Import Dependencies**
+   ```typescript
+   import { PrismaClient as CentralPrismaClient } from '../prisma/generated-central/client';
+   import knex, { Knex } from 'knex';
+   import { createDecipheriv } from 'crypto';
+   ```
+
+2. **Decrypt Password**
+   ```typescript
+   function decryptPassword(encryptedPassword: string): string {
+     // AES-256-CBC decryption
+   }
+   ```
+
+3. **Create Tenant Connection**
+   ```typescript
+   function createTenantKnexConnection(tenant: any): Knex {
+     const decryptedPassword = decryptPassword(tenant.dbPassword);
+     return knex({ /* config */ });
+   }
+   ```
+
+4. **Run Migrations**
+   ```typescript
+   const [batchNo, log] = await tenantKnex.migrate.latest();
+   ```
+
+5. **Report Results**
+   ```typescript
+   console.log(`✅ Ran ${log.length} migrations`);
+   ```
+
+## 🧪 Testing the Implementation
+
+### 1. Verify Scripts Are Available
+```bash
+cd /root/neo/backend
+npm run | grep migrate
+```
+
+Expected output:
+```
+migrate:make
+migrate:latest
+migrate:rollback
+migrate:status
+migrate:tenant
+migrate:all-tenants
+```
+
+### 2. Test Creating a Migration
+```bash
+npm run migrate:make test_migration
+```
+
+Should create a file in `migrations/tenant/`
+
+### 3. Check Status (if tenants exist)
+```bash
+npm run migrate:status
+```
+
+### 4. Test Single Tenant Migration (if tenants exist)
+```bash
+npm run migrate:tenant <your-tenant-slug>
+```

+
+2. **Knex Configuration**
+   - Uses existing `knexfile.js`
+   - Same migration table: `knex_migrations`
+   - Compatible with existing migrations
+
+3. **Prisma Central Client**
+   - Scripts use central DB to fetch tenant list
+   - Same encryption/decryption logic as backend services
+
+## 🚦 Next Steps
+
+### To Use This Implementation:
+
+1. **Ensure Environment Variables**
+   ```bash
+   export DB_ENCRYPTION_KEY="your-32-character-secret-key!!"
+   ```
+
+2. **Generate Prisma Client** (if not already done)
+   ```bash
+   cd /root/neo/backend
+   npx prisma generate --schema=prisma/schema-central.prisma
+   ```
+
+3. **Check Current Status**
+   ```bash
+   npm run migrate:status
+   ```
+
+4. **Create Your First Migration**
+   ```bash
+   npm run migrate:make add_my_feature
+   ```
+
+5. **Test and Apply**

+# Tenant Migration Scripts
+
+This directory contains scripts for managing database migrations across all tenants in the multi-tenant platform.
+
+## Available Scripts
+
+### 1. Create a New Migration
+
+```bash
+npm run migrate:make <migration_name>
+```
+
+Creates a new migration file in `migrations/tenant/` directory.
+
+**Example:**
+```bash
+npm run migrate:make add_status_field_to_contacts
+```
+
+### 2. Migrate a Single Tenant
+
+```bash
+npm run migrate:tenant <tenant-slug-or-id>
+```
+
+Runs all pending migrations for a specific tenant. You can identify the tenant by its slug or ID.
+
+**Example:**
+```bash
+npm run migrate:tenant acme-corp
+npm run migrate:tenant cm5a1b2c3d4e5f6g7h8i9j0k
+```
+
+### 3. Migrate All Tenants
+
+```bash
+npm run migrate:all-tenants
+```
+
+Runs all pending migrations for **all active tenants** in the system. This is useful when:
+- You've created a new migration that needs to be applied to all tenants
+- You're updating the schema across the entire platform
+- You need to ensure all tenants are up to date
+
+**Output:**
+- Shows progress for each tenant
+- Lists which migrations were applied
+- Provides a summary at the end
+- Exits with error code if any tenant fails
+
+### 4. Rollback Migration (Manual)
+
+```bash
+npm run migrate:rollback
+```
+
+⚠️ **Warning:** This runs a rollback on the **default database** configured in `knexfile.js`. For tenant-specific rollbacks, you'll need to manually configure the connection.
+
+## Migration Flow
+
+### During New Tenant Provisioning
+
+When a new tenant is created via the API, migrations are automatically run as part of the provisioning process:
+
+1. Tenant database is created
+2. `TenantProvisioningService.runTenantMigrations()` is called
+3. All migrations in `migrations/tenant/` are executed
+
+### For Existing Tenants
+
+When you add a new migration file and need to apply it to existing tenants:
+
+1. Create the migration:
+   ```bash
+   npm run migrate:make add_new_feature
+   ```
+
+2. Edit the generated migration file in `migrations/tenant/`
+
+3. Test on a single tenant first:
+   ```bash
+   npm run migrate:tenant test-tenant
+   ```
+
+4. If successful, apply to all tenants:
+   ```bash
+   npm run migrate:all-tenants
+   ```
+
+## Migration Directory Structure
+
+```

+│   └── migrate-all-tenants.ts    # All tenants migration
+└── knexfile.js                   # Knex configuration
+```
+
+## Security Notes
+
+### Database Password Encryption
+
+Tenant database passwords are encrypted in the central database using AES-256-CBC encryption. The migration scripts automatically:
+
+1. Fetch tenant connection details from the central database
+2. Decrypt the database password using the `DB_ENCRYPTION_KEY` environment variable
+3. Connect to the tenant database
+4. Run migrations
+5. Close the connection
+
+**Required Environment Variable:**
+```bash
+DB_ENCRYPTION_KEY=your-32-character-secret-key!!
+```
+
+This key must match the key used by `TenantService` for encryption.
+
+## Troubleshooting
+
+### Migration Fails for One Tenant
+
+If `migrate:all-tenants` fails for a specific tenant:
+
+1. Check the error message in the output
+2. Investigate the tenant's database directly
+3. Fix the issue (manual SQL, data cleanup, etc.)
+4. Re-run migrations for that tenant: `npm run migrate:tenant <slug>`
+5. Once fixed, run `migrate:all-tenants` again to ensure others are updated
+
+### Migration Already Exists
+
+Knex tracks which migrations have been run in the `knex_migrations` table in each tenant database. If a migration was already applied, it will be skipped automatically.
+
+### Connection Issues
+
+If you see connection errors:
+
+1. Verify the central database is accessible
+2. Check that tenant database credentials are correct
+3. Ensure `DB_ENCRYPTION_KEY` matches the one used for encryption
+4. Verify the tenant's database server is running and accessible
+
+## Example Migration File
+
+```javascript
+// migrations/tenant/20250126000006_add_custom_fields.js
+
+exports.up = async function(knex) {
+  await knex.schema.table('field_definitions', (table) => {
+    table.boolean('is_custom').defaultTo(false);
+    table.string('custom_type', 50).nullable();
+  });
+};
+
+exports.down = async function(knex) {
+  await knex.schema.table('field_definitions', (table) => {
+    table.dropColumn('is_custom');
+    table.dropColumn('custom_type');
+  });
+};
+```
+
+## Best Practices
+
+1. **Always test on a single tenant first** before running migrations on all tenants
+2. **Include rollback logic** in your `down()` function
+3. **Use transactions** for complex multi-step migrations
+4. **Backup production databases** before running migrations
+5. **Monitor the output** when running `migrate:all-tenants` to catch any failures
+6. **Version control** your migration files
+7. **Document breaking changes** in migration comments
+8. **Consider data migrations** separately from schema migrations when dealing with large datasets
+
+## CI/CD Integration
+
+In your deployment pipeline, you can automatically migrate all tenants:
+
+```bash
+# After deploying new code
+npm run migrate:all-tenants
+```
+
+Or integrate it into your Docker deployment:
+
+```dockerfile
+# In your Dockerfile or docker-compose.yml
+CMD npm run migrate:all-tenants && npm run start:prod
+```
