How to set variable innodb_strict_mode to OFF on target

You may have come across the following error message during the course of a migration pre-check on the target server:

In InnoDB 5.6 (both in MySQL 5.6 and MariaDB 10.0/10.1) server has variable innodb_strict_mode=0 by default.
So you can create table with wrong ROW_FORMAT option and warning will be reported.
In InnoDB 5.7 (both in MySQL 5.7 and MariaDB 10.2) server has variable innodb_strict_mode=1 by default.
Migration from source, hosted with previous version of InnoDB will not be possible to target
with current version of InnoDB and error will be issued if innodb_strict_mode is set to default.
Set variable innodb_strict_mode to OFF on target to avoid the migration errors.
Here is the link describing the problem
https://jira.mariadb.org/browse/MDEV-11305

Upon investigation, our Support Team has come to the conclusion that this error is due to the default enabling of Strict mode in the newer versions of MySQL/MariaDB.

For Linux: Set variable innodb_strict_mode to OFF

1. First, we have to connect to the target server with the help of SSH.
2. Next, we add the innodb_strict_mode to MySQL by opening the /etc/my.cnf in a text editor.
3. Then, we have to add innodb_strict_mode=OFF under the [mysqld] section.
4. After that, save the changes and close the text editor.
5. Now, it is time to restart the MySQL service with the command:
6. # service mysql restart || service mariadb restart || service mysqld restart
7. Finally, it is time to proceed with the migration.

For Windows: Set variable innodb_strict_mode to OFF

1. First, we have to connect to the target server with the help of RDP.
