If you receive error messages that state "Please upgrade the Content Integrator" or "The app needs to be upgraded" then use the following procedure. 

To change the setting to the required value, perform the following steps:

  1. Download and install the SharePoint Online Management Shell from the Official Microsoft Download Center here.
  2. Open the SharePoint Management Shell and connect to your SharePoint Online by executing the following command:

Finally, wait for few hours and install the Office 365 application. It should work with the new SharePoint tenant.
