Duplicate an existing theme
Perform this task if you want to create a new theme that is very similar to an existing one, or if you want to create a draft copy of an active theme.
Tip: If you want to edit a theme but are not ready to make
your changes live, duplicate the theme you want to edit, and make your changes
in the duplicate. Set the duplicate as the active theme for the community when
you want to make your changes live.
Note: This task cannot be
performed by Author or Analyst users.
