First, many thanks for the plugin, that works like a charm.
Second, I was initially unable to get it working because I did not understand that the 2 files (installer.php and the other with the backup) have to be uploaded to the location of the new website.
But I got all replies looking into this tutorial found on you tube:
that is much more detailed.
I suggest you place a link to this tutorial in your support page. It will save a lot of time to beginners like me.
Best and thanks again. I am going to try to do a donation
