HPE will officially stopped promoting the legacy interface.
In the application launcher there is no legacy interface function anymore but it is still there if user really need it.
User can launch the legacy interface by running the following command :
C:\Program Files (x86)\HPE\VM Explorer\VMX.exe /gui
However HPE have announced that this option will be removed, likely by the end of the year 2016.
Note:Customers should also be aware that all new features are going to be developed only in the new web user interface .
