title: Is it possible to simply export data from mongodb 3.2 and import it to mognodb 3.4?
body: <p>I have done this ( exported from MongoDB 3.2 and imported it into a MongoDB 3.4 instance ). currently, everything is okay and there are no problems reported by our users. but I am sort of worried about problems in the future. unfortunately, I'm not an expert MongoDB administer.</p>
  <p>So I need some help.
  How can I run a kind of health check on the new instance to make sure everything is OK?</p>
  <p>I've set up a new MongoDB server and imported data from my old server. then, I changed the database host and credentials in my application settings.</p>
