# Email Migration Script # Email Migration Script
A Python script to migrate emails from one IMAP account to another, preserving folder structure and metadata. A Python script to migrate emails from one IMAP account to another with flexible folder organization options.
## Features
- **Flexible Import Options**: Choose between organized folder structure or consolidated inbox
- **Folder Filtering**: Include/exclude specific folders from migration
- **Metadata Preservation**: Maintain email flags, dates, and other metadata
- **Batch Processing**: Configurable batch sizes for optimal performance
- **Comprehensive Logging**: Detailed logs for monitoring and troubleshooting
- **SSL Security**: Secure connections with SSL/TLS support
## Quick Start ## Quick Start
1. Edit .env file with your email credentials 1. **Install**: No dependencies required - uses Python standard library
2. Run: python3 email_migration.py 2. **Configure**: Copy `.env.template` to `.env` and add your email credentials
3. **Run**: `python3 email_migration.py`
## Requirements ## Requirements
- Python 3.6+ (pre-installed on Linux & macOS) - Python 3.6+ (pre-installed on Linux & macOS)
- No additional dependencies required - IMAP access enabled on both email accounts
- App passwords (recommended for Gmail, Yahoo, Outlook)
## Configuration ## Import Folder Options
Edit the .env file with your email account settings.
## Important Notes ### Option 1: Organized Import (Recommended)
- Use app passwords, not regular passwords
- Test with a small folder first ```env
- Check email_migration.log for detailed logs IMPORT_FOLDER_NAME=Imported
```
**Result**: All source folders become subfolders within "Imported"
- Source `INBOX` → Destination `Imported/INBOX`
- Source `Sent` → Destination `Imported/Sent`
- Source `Drafts` → Destination `Imported/Drafts`
**Benefits**:
- Preserves original folder structure
- Keeps imported emails separate from existing emails
- Easy to locate and organize imported content
### Option 2: Consolidated Import
```env
IMPORT_FOLDER_NAME=
```
**Result**: All emails go directly to destination INBOX
- All source folders → Destination `INBOX`
**Benefits**:
- Simple single-folder result
- Useful for merging multiple accounts
- Good for basic email consolidation
## Configuration Guide
### Email Account Setup
```env
# Source account (migrating FROM)
SOURCE_IMAP_SERVER=imap.gmail.com
SOURCE_EMAIL=old@gmail.com
SOURCE_PASSWORD=your_app_password
# Destination account (migrating TO)
DEST_IMAP_SERVER=imap.gmail.com
DEST_EMAIL=new@gmail.com
DEST_PASSWORD=your_app_password
```
### Common IMAP Servers
| Provider | IMAP Server | Port | SSL |
|----------|-------------|------|-----|
| Gmail | `imap.gmail.com` | 993 | Yes |
| Outlook/Hotmail | `outlook.office365.com` | 993 | Yes |
| Yahoo | `imap.mail.yahoo.com` | 993 | Yes |
| Apple iCloud | `imap.mail.me.com` | 993 | Yes |
### App Password Setup
**Gmail**: Google Account → Security → App Passwords
**Yahoo**: Account Security → Generate app password
**Outlook**: Account Security → App passwords
⚠️ **Important**: Use app passwords, not regular login passwords!
## Advanced Configuration
### Folder Filtering
```env
# Only migrate specific folders
INCLUDE_FOLDERS=INBOX,Sent,Important
# Skip unwanted folders
EXCLUDE_FOLDERS=Trash,Spam,Junk
```
### Performance Tuning
```env
# Batch size (emails per batch)
BATCH_SIZE=50 # Default balance
BATCH_SIZE=10 # Conservative (slow connections)
BATCH_SIZE=100 # Aggressive (fast connections)
# Connection timeout
IMAP_TIMEOUT=60 # Default
IMAP_TIMEOUT=120 # Slow connections
```
### Logging and Debugging
```env
LOG_LEVEL=INFO # Normal operation
LOG_LEVEL=DEBUG # Detailed troubleshooting
LOG_LEVEL=ERROR # Errors only
```
## Usage Examples
### Example 1: Full Gmail Migration with Organization
```bash
# .env configuration
SOURCE_EMAIL=old@gmail.com
DEST_EMAIL=new@gmail.com
IMPORT_FOLDER_NAME=OldAccount
EXCLUDE_FOLDERS=Trash,Spam
# Run migration
python3 email_migration.py
```
### Example 2: Test Migration (INBOX only)
```bash
# .env configuration
INCLUDE_FOLDERS=INBOX
BATCH_SIZE=10
LOG_LEVEL=DEBUG
# Run migration
python3 email_migration.py
```
### Example 3: Consolidate Multiple Accounts
```bash
# .env configuration
IMPORT_FOLDER_NAME=
# This puts all emails in main INBOX
# Run migration
python3 email_migration.py
```
## Monitoring Progress
The script provides detailed logging in multiple places:
1. **Console Output**: Real-time progress updates
2. **Log File**: `email_migration.log` with detailed information
3. **Final Summary**: Complete migration statistics
Example output:
```
Email Migration Script
==================================================
[INFO] Import folder configuration: All emails will be imported to subfolders within "Imported"
[INFO] Found 5 folders to process
[INFO] Processing folder: INBOX
[INFO] Migrating 'INBOX' -> 'Imported/INBOX'
[INFO] Downloaded 150/150 messages from INBOX
[INFO] Uploaded 150/150 messages to Imported/INBOX
[INFO] Folder 'INBOX' -> 'Imported/INBOX' completed: 150 downloaded, 150 uploaded
Migration completed!
Folders processed: 5
Total emails downloaded: 1250
Total emails uploaded: 1250
Errors encountered: 0
```
## Troubleshooting
### Common Issues
**Authentication Failed**
- Use app passwords instead of regular passwords
- Enable IMAP access in email account settings
- Check server settings and ports
**Connection Timeout**
- Increase `IMAP_TIMEOUT` value
- Reduce `BATCH_SIZE` for stability
- Check network connection
**Folder Creation Failed**
- Verify destination account has folder creation permissions
- Check for special characters in folder names
- Some providers have folder name restrictions
**Partial Migration**
- Check logs in `email_migration.log`
- Re-run script - it will skip already migrated emails
- Use `INCLUDE_FOLDERS` to retry specific folders
### Getting Help
1. **Enable Debug Logging**: Set `LOG_LEVEL=DEBUG`
2. **Check Log File**: Review `email_migration.log`
3. **Test Small First**: Use `INCLUDE_FOLDERS=INBOX` and `BATCH_SIZE=10`
4. **Verify Credentials**: Test account access with email client first
## Security Notes
- Never commit `.env` file to version control
- Use app passwords instead of account passwords
- Ensure SSL is enabled (`*_IMAP_USE_SSL=True`)
- Store credentials securely
- Test with non-critical accounts first
