title: Can we retrive localstorage ,even we use sqlite storage in ionic 3 app
body: <p>I already have a running App in Ionic 2 beta, and I am using local storage to store logged in <code>user_id</code> to check if the user is logged in or not.
  Now I'll switch the app into Ionic 3, and now i am using SQLite storage of Ionic, so problem is, I don't want to ask for login again to my users after update the app from app store. I want to get device local storage and make entry in SQLite and remove.</p>
  
  <p>Here what I do for Ionic 2 beta app</p>
  
  <pre><code>import { Storage, LocalStorage } from 'ionic-angular';
  
  ...
  
      constructor () {
          this.local = new Storage(LocalStorage);
      }
  
      this.local.set('user_id', user_id);
  </code></pre>
  
  <p>And in the Ionic 3 app:</p>
  
  <pre><code>import { Storage } from '@ionic/storage';
  
  ...
  
      constructor(public local: Storage) {
          this.local.get('user_id').then((user_id) =&gt; {
              console.log('USER ID: ' + user_id);
          });
      }
      ...
  </code></pre>
  
  <p>Question: Now what I want, if user update his app then system first check for local storage is already set for the app, if yes then system set them as for new app and remove them, so that user will not need to signup again after update app.</p>
  
  <p>Any idea?
  Thanks in advance.</p>
