Added comprehensive database export/import system to safely migrate SSH connection data between different server environments.
Key Features:
- SQLite export format with encrypted data migration
- Hardware fingerprint protection and re-encryption
- Field mapping between TypeScript and database schemas
- Foreign key constraint handling for cross-environment imports
- Admin user assignment for imported SSH records
- Additive import strategy preserving existing data
- File upload support for import operations
Technical Implementation:
- Complete Drizzle ORM schema consistency
- Bidirectional field name mapping (userId ↔ user_id)
- Proper encryption/decryption workflow
- Multer file upload middleware integration
- Error handling and logging throughout
Security:
- Only exports SSH-related tables (ssh_data, ssh_credentials)
- Protects admin user data from migration conflicts
- Re-encrypts sensitive fields for target hardware
- Validates export file format and version compatibility
