In many instances, there isn't a one-to-one mapping. Often, Data Pump automatically provides features that used
to require a parameter in the legacy utilities. For example, whereas you used to have to specify DIRECT=Y to get a direct
path export, Data Pump automatically uses direct path whenever possible.

Data Pump Mapping to the imp Utility
As with Data Pump export, Data Pump import often doesn't have a one-to-one mapping of the legacy utility
parameter. Data Pump import automatically provides many features of the old imp utility. For example, COMMIT=Y isn't
required because Data Pump import automatically commits after each table is imported. Table 8-4 describes how the
legacy import parameters map to Data Pump import.
