I see a couple things here.

1.) It does not appear that you emptied the table before importing your backup. Since the two databases used different table prefix settings you can safely delete the tables that just have the wp_ prefix (the ones not from your import).

2.) Next you will need to update the $table_prefix setting in your wp-config.php file to reflect the table names from your import.

Once you have updated the table prefix you should see the content imported shown in your Wordpress installation.

Hello, dear! Thanks for the answer I modify table_prefix which name? Something else concludes the migration with plugin Duplicator and see how that my blog http://104.131.5.96 (blank) normal would be like this http://www.estranhos.info What to do to make this right? Very thanks.
