Upgrading MySQL to 5.7 or MariaDB to 10.2

• Make sure that 'mysql_upgrade' command is run
• Check if the following tables are created: innodb_index_stats, innodb_table_stats, slave_master_info, slave_relay_log_info, slave_worker_info

If one or some of the above tables are missing, create them manually using the below queries:
