Importing questions from a Question2Answer (Q2A) test database into a new installation involves exporting and importing specific tables. The primary tables to import include qa_posts, qa_categories, qa_posts_tags, and qa_users if user information needs preservation. Ensure data integrity and update configuration settings in the new installation. Backing up both databases beforehand is advisable. If unsure, seek assistance from someone experienced in database management or Q2A administration.
