title: SQL import only different records
body: <p>So sorry if this has been answered before, but I cannot find an answer anywhere. I have a SQL database on server "A" that has had updates etc etc on it at the same time the same database is on server "B".</p>
  
  <p>Now the issues is, some websites moved over sooner than others and those were being updated etc on server "B" while the other websites (maybe 2 or 3 weeks worth of signups) where being updated on server "A."</p>
  
  <p>Question is, I can't do an import from server "A's" .bak file to server "B's" cause I lose all of server B's data. Anyway to only import data that is different to server "B" from "A?" Make sense?</p>
  
  <p>Thank you in advance...</p>
