1. A method of migrating data between a first system and a second system, comprising:
receiving a migration task of migrating data from the first system to the second system;
determining whether upper-layer interfaces of an upper-layer interface layer corresponding to the migration task belong to data acquisition or data synchronization;
calling, for the upper-layer interfaces belonging to data acquisition, underlying operation interfaces of the first system through an abstract interface class layer to acquire data from the first system; and
calling, for the upper-layer interfaces belonging to data synchronization, the underlying operation interfaces of the second system through the abstract interface class layer to synchronize the data acquired from the first system to the second system.
