There are two ways to upgrade an instance that has already been created.
     One is to increment the version number and create a new instance
     (if it becomes a new instance (with empty content)).
    The other is to increase the version number,
    select the version you want to copy and
    copy it (when modifying the instance contents)
     This is under consideration and not available in the current version

     A version consists of a major number, a minor number, and a revision.

(1) New instance version upgrade
      Click New Instance from the [File] menu and select the model name
      and instance name to be upgraded. In the figure below, version 1.0.0
      of the instance communication protocol has already been created,
      so change the version major, minor,
      and revision. Here we have revision 1.　

      Click the New button to create a new model.

      The administration screen is displayed first.
     

       The instance screen will be displayed when you click the instance
      of the tab or "Move to instance screen" at the top right of the screen.

  (2) Copy instance version upgrade
        The current version is under consideration and
        the copy version button is not available
