+# Live Data Migration Script
+
+This script automates the migration of live server data from an SQL backup file into the current Django development environment.
+
+## Features
+
+✅ **Comprehensive Error Handling**: Handles all schema and data integrity issues  
+✅ **Automatic Rollback**: Restores previous database state on failure  
+✅ **Data Integrity Verification**: Validates imported data and counts records  
+✅ **Admin User Management**: Resets admin credentials for easy access  
+✅ **Backup Creation**: Creates backup before migration  
+✅ **Docker Integration**: Seamlessly works with Docker containers  
+
+## Usage
+
+### Basic Usage
+```bash
+./migrate_live_data.sh
+```
+*Uses default backup file: `fbf-backup.sql`*
+
+### With Custom Backup File
+```bash
+./migrate_live_data.sh /path/to/your/backup.sql
+```
+
+### Show Help
+```bash
+./migrate_live_data.sh --help
+```
+
+## What the Script Does
+
+1. **Prerequisites Check**: Verifies Docker, docker-compose, and required files
+2. **Backup Validation**: Ensures the SQL backup file is valid
+3. **Container Management**: Starts necessary Docker containers
+4. **Database Backup**: Creates backup of current database
+5. **Database Reset**: Drops and recreates the target database
+6. **Data Import**: Imports the live SQL dump
+7. **Django Migrations**: Applies any pending Django migrations
+8. **Data Verification**: Checks data integrity and counts records
+9. **Admin Setup**: Configures admin user with known credentials
+10. **Static Files**: Collects static files for the application
+
+## Migration Results
+
+After successful migration, you'll have access to:
+
+- **Application**: http://localhost:8008 (or your configured port)
+- **Admin Panel**: http://localhost:8008/admin (or your configured port)
+- **Admin Login**: username `admin`, password `admin`
+
+The script will display detailed statistics about the imported data, including:
+- Number of records imported per table
+- Data integrity verification results
+- Any warnings or issues encountered during migration
+
+## Data Verification
+
+The script automatically verifies data integrity by:
+- Counting records in all major tables
+- Checking for NULL values in critical fields
+- Displaying import statistics for verification
+
+## Error Handling
+
+- **Automatic Rollback**: If migration fails, the script automatically restores the previous database state
+- **Comprehensive Logging**: Color-coded output shows progress and any issues
+- **Backup Protection**: Current database is backed up before any changes
+
+## Files Created
+
+- `pre_migration_backup_YYYYMMDD_HHMMSS.sql`: Backup of database before migration
+- `.last_backup_file`: Temporary file tracking the backup location (auto-cleaned)
+
+## Requirements
+
+- Docker and Docker Compose
+- Valid SQL backup file (e.g., `fbf-backup.sql`) in the project root
+- `docker-compose.yaml` configuration file
+- Sufficient disk space for database backup and import
+
+## Troubleshooting
+
+### Container Issues
+```bash
+docker-compose down
+docker-compose up -d
+```
+
+### View Logs
+```bash
+docker-compose logs -f web
+docker-compose logs -f db
+```
+
+### Manual Database Access
+```bash
+docker-compose exec db psql -U fbf -d db_fbf
+```
+
+## Script Features
+
+- **🎨 Colored Output**: Easy-to-read progress indicators
+- **🔄 Progress Tracking**: Real-time status updates
+- **📊 Data Verification**: Automatic integrity checks
+- **🛡️ Safe Rollback**: Protection against data loss
+- **📝 Comprehensive Logging**: Detailed operation logs
+
+## Version
+
+**Version 1.0** - Fully automated migration with error handling and rollback capabilities.
