Windows OS MariaDB 10.2 to 10.11.5

I will be moving the database files from a Windows MariaDB 10.2 server to another Windows Server running 10.11.5. On the new server after I copy the files over and start the service, I need to run the MariaDB-Upgrade command. My question is will this change the structure of tables at all? I am never upgraded MariaDB before and worried it may break some of our code or other compatibility issues.
