Perfect for it’s designed purpose

Just finished transferring my third site to a new location. Duplicator worked flawlessly each time. Note that it isn’t a simple backup program where you can migrate your database or certain files. It destroys everything at the destination (automatically if you have pro and manually via FTP otherwise). I’ve used this for new stage and development sites and it is incredibly simple to use. I’ve also used it for a wholesale update to production sites (new themes, etc.). Yes, you can do this manually with more sense of control, but easy and reliable seems better to me.
