然而，如果修改影响流程的业务逻辑，流程实例只有流程导航没有到达任何修改时才能迁移。

However, if the changes affect the business logic of a process, a process instance can be migrated only if the process navigation has not reached any of these changes.

在流程实例迁移后，已经导航的活动并不受迁移的影响。

The activities that have already been navigated when the process instance is migrated are not affected by the migration.

企业订单实例表明，引入导航树路径规划机制可以使迁移实例获得更有针对性的迁移路线，避免盲目迁移。

The order form example shows that migrating instance can acquire an effective migrating path and avoid vain migration by means of the migrating instance path planning mechanism.
