If the major and minor version are the same or close for example [5.7 to 5.6], then the migration should work without issues.  A version pair of [5.7 to 5.1] is more likely to cause issues unless you have a very simple setup.  If the versions are too far apart work with your hosting provider to upgrade the MySQL engine on this server.<br/><br/>   <b>MariaDB:</b> If see a version of 10.N.N then the database distribution is a MariaDB flavor of MySQL.   While the distributions are very close there are some subtle differences.   Some operating systems will report the version such as "5.5.5-10.1.21-MariaDB" showing the correlation of both.

It is highly recommended that you continue with the install process and closely monitor the installer-log.txt file along with the install report found on step 3 of the installer.  Be sure to look for any notices/warnings/errors in these locations to validate the install process did not detect any errors.
