  batches(BATCH_SIZE) do |offset|
    discussions = mysql_query(<<-SQL
      SELECT pid as tid, topic_id, post_title as title, post as raw,
             FROM_UNIXTIME(post_date) as created_at, author_id
      FROM iBB_posts
      WHERE new_topic = 1
      ORDER BY post_date ASC
      LIMIT #{BATCH_SIZE} OFFSET #{offset};
    SQL
    ).to_a

    break if discussions.empty?

    create_posts(discussions, total: total_count, offset: offset) do |discussion|
      {
        id: "topic-#{discussion['tid']}",
        user_id: user_id_from_imported_user_id(discussion['author_id']) || Discourse::SYSTEM_USER_ID,
        title: format_title(discussion['title']),  # Ensure titles are properly formatted
        raw: discussion['raw'],

        post_number: 1
      }
    end
  end
end
def format_title(title)
  return "Untitled Topic" if title.nil? || title.strip.empty?
  CGI.unescapeHTML(title)
end
def import_replies
  puts "\n📌 Importing Replies..."
  total_count = mysql_query("SELECT count(*) FROM iBB_posts WHERE new_topic = 0;").first['count']

  batches(BATCH_SIZE) do |offset|
    comments = mysql_query(<<-SQL
      SELECT pid, topic_id, post as raw, FROM_UNIXTIME(post_date) as created_at, author_id

    break if comments.empty?

    create_posts(comments, total: total_count, offset: offset) do |comment|
      topic_id = topic_lookup_from_imported_post_id("topic-#{comment['topic_id']}")
      next unless topic_id

      {
