title: Merging Two databases with the same exact structure [MYSQL]
body: <p>I just had my site hacked and they were able to do some damage to my current database.</p>
  
  <p>Anyway, I have a backup from few days ago. The problem is that the current database had a few thousand more posts and threads / users. </p>
  
  <p>I am simply wondering how I could possibly go about merging the two databases?</p>
  
  <p>The two databases have the exact structure, and I want the backup to overwrite any record from the current database, just that I want the current database to populate any new records like posts, threads, users and such. </p>
  
  <p>I know you can merge two tables, if they have the exact structure, but what about two databases that have the same structure? </p>
