The only functioning easy WP migration method

I used to work with Joomla. But sometimes this needs much effort to get things right (especially after a large update). I wanted to make a website about my vacations to the USA and started with a free WordPress site. That appeared to be much more easy than Joomla and then I decided to rebuild my own website with WordPress. But it could not be done directly online because I need maximum uptime, so I tried to install XAMPP on a Mac, which was not quite easy. But after I copied my whole website from Joomla to WordPress (it took me about one month) I wanted to upload it to the external server. And that gave me a big headache. Everything I found on the internet gave to much trouble. But then I stumbled upon All-in-One WP Migration and it did the job without any problems. Just installed a new version of WP on the server, did an export from my Mac and an import on the server and everything worked at once. Thanx!
