Abstract
The disclosure relates to the communications technologies field, and in particular, to a data migration method and apparatus, to implement data migration in an enclave page cache (EPC), to improve consistency between data of an application program before migration and that after migration. The method includes: obtaining, by a source host, a migration instruction, where the migration instruction is used to instruct to migrate a target application created with an enclave to a destination host; invoking, by the source host, a migration control thread preset in the enclave of the target application, to write running status data of the target application in an EPC into target memory of the source host, where the target memory is an area other than the EPC in memory of the source host; and sending, by the source host, the running status data of the target application in the target memory to the destination host.
