title: Merge tables without overwriting existing ones in mysql phpmyadmin
body: <p>I was having a "coming soon" page with a sign up form. Since a couple of weeks I've switched to another web hosting and continue working on my new site at my new host, but continued to let the visitors sign up at my old host.</p>
  
  <p>Now my have pointed my domain to my new hosting and want to export all new subscribers and import them into the new DB. Some rows might use same ID.</p>
  
  <p>How can I easily export and merge a table from the old DB to the new one? Please note I don't wan't it to overwrite any row that has the same ID, if it does, I want it to add a new row instead.</p>
  
  <p>I've tried exporting my table "wp_csp3_subscribers" from my old DB and imported it in my new one. But get an error saying ID already exists.</p>
