|
|
|
### Single Account Migration
|
|
|
|
```bash
|
|
# Basic migration
|
|
./mail-migrator --src "user1:pass1@imap.old.com:993" \
|
|
--dst "user1:pass1@imap.new.com:993"
|
|
|
|
# With insecure mode (trust self-signed certs)
|

|
--insecure
|
|
|
|

|
|
./mail-migrator --src "user1:pass1@imap.old.com:993" \
|
|
--dst "user1:pass1@imap.new.com:993" \
|
|
--insecure \
|
|
--resume \
|
|
--log migration.log
|
|
```
|
|
|
|
### Batch Migration
|
|
|
|
Buat file CSV dengan format: `source,destination`
|
|
|
|
**accounts.csv:**
|
|
```csv
|
|
user1:pass1@old.com:993,user1:newpass1@new.com:993
|
|
user2:pass2@old.com:993,user2:newpass2@new.com:993
|
|
user3:pass3@old.com:993,user3:newpass3@new.com:993
|
|
```
|
|
|
|
```bash
|
|
# Batch migration
|
|
./mail-migrator --batch accounts.csv --insecure --resume --log batch.log
|
|
```
|
|
|
|
## Command Line Options
|
|
|
|
| Flag | Description | Default |
|
|
|------|-------------|---------|
|
|
| `--src` | Source IMAP URL (user:pass@host:port) | - |
|
|
| `--dst` | Destination IMAP URL (user:pass@host:port) | - |
|
|
| `--batch` | CSV file with src,dst entries for batch migration | - |
|
|
| `--insecure` | Allow insecure TLS (trust self-signed certs) | false |
|
|
| `--resume` | Resume incomplete migrations | false |
|
|
| `--state` | Path to state DB (Bolt) | state.db |
|
|
| `--log` | Path to log file (optional) | - |
|
|
|
|
## URL Format
|
|
|
|
IMAP URL format: `username:password@hostname:port`
|
|
|
|
**Examples:**
|
|
- `john:secret123@mail.example.com:993` (IMAPS)
|
|
- `jane:mypass@imap.gmail.com:993` (Gmail)
|
|
- `user@domain.com:password@mail.server.com:143` (IMAP plain)
|
|
|
|
**Port defaults:**
|
|
- Port 993: IMAPS (TLS/SSL)
|
|
- Port 143: IMAP (plain/STARTTLS)
|
|
|
|
## Resume Functionality
|
|
|
|
Aplikasi menggunakan BoltDB untuk menyimpan state migrasi:
|
|
|
|
- **State Key**: `source|destination|mailbox`
|
|
- **Tracking**: Last migrated UID per mailbox
|
|
- **Resume**: Otomatis lanjut dari UID terakhir yang sukses
|
|
- **File**: Default `state.db` (bisa diubah dengan `--state`)
|
|
|
|
## Logging
|
|
|
|
- **Console**: Selalu aktif dengan timestamp
|
|
- **File**: Optional dengan flag `--log filename.log`
|
|
- **Format**: `[timestamp] [level] message`
|
|
- **Levels**: INFO, WARN, ERROR, DEBUG
|
|
|
|
## Error Handling
|
|
|
|
- **Connection errors**: Retry dengan backoff
|
|
- **Authentication**: Clear error message
|
|
- **Mailbox errors**: Skip dan lanjut ke mailbox berikutnya
|
|
- **Message errors**: Skip message yang corrupt, lanjut ke berikutnya
|
|
- **Batch errors**: Error di satu akun tidak stop seluruh batch
|
|
|
|
## Performance
|
|
|
|
- **Batch size**: 50 messages per batch (configurable dalam code)
|
|
- **Memory**: Efficient streaming untuk message besar
|
|
- **Concurrent**: Single-threaded untuk stability
|
|
- **Resume**: Minimal overhead dengan UID tracking
|
|
|
|
## Troubleshooting
|
|
|
|
### Common Issues
|
|
|
|
**1. Certificate Errors**
|
|
```
|
|
x509: certificate signed by unknown authority
|
|
```
|
|
**Solution**: Gunakan flag `--insecure`
|
|
|
|
**2. Authentication Failed**
|
|
```
|
|
login failed: Invalid credentials
|
|
```
|
|
**Solution**:
|
|
- Cek username/password
|
|
- Untuk Gmail: gunakan App Password, bukan password biasa
|
|
- Cek apakah IMAP enabled di server
|
|
|
|
**3. Connection Timeout**
|
|
```
|
|
dial failed: i/o timeout
|
|
```
|
|
**Solution**:
|
|
- Cek hostname dan port
|
|
- Cek firewall/network connectivity
|
|
- Cek apakah server support IMAP
|
|
|
|
**4. Mailbox Not Found**
|
|
```
|
|
select source INBOX: Mailbox doesn't exist
|
|
```
|
|
**Solution**:
|
|
- Cek apakah mailbox ada di source
|
|
- Beberapa server case-sensitive untuk nama mailbox
|
|
|
|
### Debug Mode
|
|
|
|
Untuk debug lebih detail, edit code dan set:
|
|
```go
|
|
logrus.SetLevel(logrus.DebugLevel)
|
|
```
|
|
|
|
## Examples
|
|
|
|
### Gmail to Gmail
|
|
```bash
|
|
./mail-migrator --src "olduser@gmail.com:apppass1@imap.gmail.com:993" \
|
|
--dst "newuser@gmail.com:apppass2@imap.gmail.com:993" \
|
|
--insecure --resume --log gmail-migration.log
|
|
```
|
|
|
|
### Office365 Migration
|
|
```bash
|
|
./mail-migrator --src "user@old.com:password@outlook.office365.com:993" \
|
|
--dst "user@new.com:password@outlook.office365.com:993" \
|
|
--resume --log o365-migration.log
|
|
```
|
|
|
|
### Self-hosted with Self-signed Cert
|
|
```bash
|
|
./mail-migrator --src "user:pass@mail.old.local:993" \
|
|
--dst "user:pass@mail.new.local:993" \
|
|
--insecure --resume
|
|
```
