What causes this issue?

The number of article hierarchy levels defined in Customizing for the
article hierarchy is too low. This can result in data loss during the
migration process, due to the following differences between the old and
new article hierarchy:
In the old article hierarchy, the number of hierarchy levels is
restricted to maximum seven levels.
In the new article hierarchy, the number of hierarchy levels is not
restricted.
If you define fewer than seven hierarchy levels in Customizing for the
new article hierarchy, the data from article hierarchies with more than
seven hierarchy levels will be lost.

System Response

The system cancels migration.
