|
|
### Schema Migrations
|
|
|
|
Database migrations are managed automatically:
|

|
```bash
|
|
# Run migrations
|
|
cd api
|
|
npm run db:migrate
|
|
|
|
# Rollback if needed
|
|
npm run db:rollback
|
|
```
|
|
|
|
### Manual Migration Steps
|
|
|
|
1. **Backup Database**: Always backup before migration
|
|
```bash
|
|
pg_dump sankofa > backup_$(date +%Y%m%d).sql
|
|
```
|
|
|
|
2. **Run Migrations**: Execute migration scripts
|
|
```bash
|
|
npm run db:migrate
|
|
```
|
|
|
|
3. **Verify Migration**: Check migration status
|
|
```bash
|
|
npm run db:migrate:status
|
|
```
|
|
|
|
4. **Test Application**: Verify application functionality
|
|
5. **Monitor**: Watch for errors post-migration
|
|
|
|
### Data Migration

|
|
|
For data migrations:
|
|
|
|
1. **Export Data**: Export from source
|
|
2. **Transform Data**: Apply necessary transformations
|
|
3. **Import Data**: Import to new schema

|
2. **Update `.env` Files**: Update environment variables
|
|
3. **Test Configuration**: Verify configuration is correct
|
|
4. **Deploy**: Deploy updated configuration
|
|
|
|
### Configuration Files
|
|
|
|
```bash
|
|
# Backup current configuration
|
|
cp .env.local .env.local.backup
|
|
