Trouble migrating php 2 hhvm, mysql from 5.6 to 5.7.8?

Question

PHP

Transferred to another hosting (from php transferred to hhvm, and from 5.6 to 5.7.8 mysql) and crashes like this when entering phpmyadmin SQL query
error : Change SHOW VARIABLES LIKE 'character_set_results' MySQL response:

#1146 - Table 'performance_schema.session_variables' doesn't exist

Adding to some tables does not work.

Answer 1

The transfer is incorrect. MySQL 5.5 also does not have a "performance_schema.session_variables" table.

Answer 2

What is the version of PhpMyAdmin?

Answer 3

in general, cleaning the database helped, importing again, adding default values ​​​​everywhere
