You can upgrade your existing plug-ins created with the vSphere Web Client SDK 5.5.x to be compatible with vSphere 6.5 by applying changes to your JavaScript code and plugin.xml manifest files.

You must apply all changes required to upgrade plug-ins created with the vSphere Web Client SDK 6.0 before you proceed with the next three changes.

To upgrade your existing plug-ins that are created with the vSphere Web Client SDK 5.5.x, you must adapt the plug-ins to the following additional changes:

Use the WEB_PLATFORM.setDialogSize() and WEB_PLATFORM.setDialogTitle() JavaScript functions introduced to the APIs for vSphere 6.0 to change the dialog size and title at runtime.

Use the <dialogIcon> and <showCloseButton> XML elements in your plugin.xml manifest files to specify an icon and control the close button visibility for the dialog boxes and Summary view portlets.

Use the WEB_PLATFORM.openModalDialog() function introduced to the JavaScript APIs for vSphere 6.0 to open a modal dialog box from within an HTML view.
