Data Migration

This function helps you migrate data from Alibaba Cloud MaxCompute to Huawei Cloud DLI. It supports full migration and incremental migration of metadata.

For details about the constraints and precautions of data migration, see Before You Start.

Data Verification

MgC can verify the consistency of data migrated from various big data computing and storage engines, such as Hive, HBase, Doris, and MaxCompute. Consistency verification ensures data accuracy and reliability and enables you to migrate big data to Huawei Cloud with confidence.

For details about the precautions, constraints, and verification methods of data verification, see Overview.
