The Configuration Type screen allows you to choose between a Direct Migration and a Agent-Based Migration:
Use the Direct Migration
if the
MySQL Migration Toolkit is installed on either the source or target
machine. The Direct Migration should not be used when the
MySQL Migration Toolkit is not located on either the source or target
machine, as it will create a large amount of network traffic and
will result in decreased performance.
Use the Agent-Based Migration
when migrating
between two server machines that do not support the use of the
MySQL Migration Toolkit. The MySQL Migration agent should be installed
on the source machine before using the Agent-Based Migration.
