Changing or moving your database is pretty easy. I suggest using Navicat MySQL for database backing up and moving.
Next Select Backups from which database you’re moving or backing up.
Now click Start. You don’t have to set anything by default, it will just make a new backup.
This is how you create backups. Moving from one database to another is very easy as well. Open your backups from the tree view. Right Click on the backup you want to copy to another database and COPY.
Now find the database you want to put the backup in. Go to it’s backups. And Paste the backup into the other databases backups section.
Now open that database backup, and restore it. As long as the database your moving too doesn’t already have the same tables, you shouldn’t have a problem.
