The following error appears during 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
Here is a list of affected subscriptions:
Strict mode is enabled on the newer versions of MySQL/MariaDB by default.
Note: Once the migration will finish, it is safe to enable back the innodb_strict_mode option in Plesk Obsidian.
