While this component did (eventually) clone my site to a new server, it still has some glitches and bugs to be worked out. A novice might not have been successful with this tool. I was able to trouble-shoot my way through the bugs, but only because of my years of knowledge about servers, mysql, and PHP. I am not hopeful for less experienced users.
The good news:
With that said, this product is poised to become one of the most useful joomla tools ever. With some software updates, JoomlaCloner can be a great product.
I'll be watching, and waiting.
