I want to take an existing live site copy it either to my local server or a staging area where I can totally develop a new site - using a new theme, different plugins etc. Then when done push or migrate new site to replace the existing site. Should I use Snapshot or Cloner or both? And can you give some advise and details on the process. Is Cloner just for Multi Site - because I am working on a single site that it not part of a multi site situation.
