title: How to add a new Objectstore to an existing indexeddb
body: <p>Can anybody tell me how to add a new objectstore to an existing indexeddb instance which has a version number in it. When I try to create a new version existing object stores are getting deleted.</p>
  
  <p>I have a version '1', which has around 10 object stores with data. When I try to open the same database with new version number, I lost the current data and object stores.</p>
  
  <p>here is what I have tried.</p>
  
  <pre><code>var _upRequest = indexedDB.open("employees");
  
      _upRequest.onsuccess = function (e) {
          var thisDb = e.target.result;
          var version = parseInt(thisDb.version)+1;
          thisDb.close();
          var openRequest = indexedDB.open("employees", version);
  
          //handle setup, this will be run by Firefox
          openRequest.onupgradeneeded = function (e) {
              console.log("running onupgradeneeded");
              var thisDb = e.target.result;
  
              //Create Employee
              if (!thisDb.objectStoreNames.contains("employee")) {
                  console.log("I need to make the employee objectstore");
                  var objectStore = thisDb.createObjectStore("employee", { keyPath: "id", autoIncrement: true });
                  objectStore.createIndex("searchkey", "searchkey", { unique: false });
              }
              thisDb.close();
          }
  
          openRequest.onsuccess = function (e) {
  
              db = e.target.result;
  
              db.onerror = function (e) {
                  alert("Sorry, an unforseen error was thrown.");
                  console.log("***ERROR***");
                  console.dir(e.target);
              }
  
              db.close();
          }
      }
