I have been sandboxing a Wordpress on my Cloudron and now I need to move it over to a special Wordpress host. What is the best approach to this? Pitfalls?
Just try BackWPup. I see no reason why it should not work. For safety, create a admin account within the current sandbox wordpress before the backup. After the migration you have to adjust stuff like email settings but you should be fine.
The backups also contain the sql dump and all the data files nicely structured, if required.
