How do we fix the “pre-migration check finishes with an error” in Plesk?

For Linux and Windows-based retail hosting service providers, Plesk is a commercial web hosting and server data center automation software. Plesk Web Admin Edition, Plesk Web Pro Edition, and Plesk Web Host Edition are the configurations that are offered. These are available for an upfront monthly or yearly fee.

We can easily manage a number of aspects of web hosting with Plesk. The tool offers some extra options in addition to the features found in every control panel.

Sometimes, during a migration pre-check on the target server, we may see the below error:

The reason behind the issue is the activation of Strict mode in newer MySQL/MariaDB versions by default. So we have to disable it. After the migration process completes, we can turn it on back.

2. Access the MySQL configuration file

   %plesk_dir%Databases\MySQL\my.iniCopy Code

   under the [mysqld] section.

   innodb_strict_mode=OFF
   <...>
4. Close it after saving the changes.
5. Utilizing Plesk Services Monitor, restart the MySQL service.
6. Continue the migration.

On Linux OS

1. We can use SSH to connect to the target server.
