How can database structure differences between two PHPBB forums be addressed during the merging process to prevent data loss?

To address database structure differences between two PHPBB forums during the merging process and prevent data loss, you can use a database migration tool or script to map and transform the data from one structure to match the other. This can involve renaming columns, converting data types, or creating new tables to accommodate the differences. 

// Example code snippet for database migration using PHP
// Connect to the source and destination databases
$source_conn = new mysqli('source_host', 'source_username', 'source_password', 'source_database');
$dest_conn = new mysqli('dest_host', 'dest_username', 'dest_password', 'dest_database');

// Query and fetch data from the source database
$source_data = $source_conn->query('SELECT * FROM source_table');
while ($row = $source_data->fetch_assoc()) {
    // Transform and insert data into the destination database
    $dest_conn->query('INSERT INTO dest_table (column1, column2) VALUES ('.$row['source_column'].', '.$row['source_column2'].')');
}

// Close connections
$source_conn->close();
$dest_conn->close();
