Migration Preparation

The CDH HBase version is earlier than or equal to the MRS HBase version.
No write, split, or merge operations can be performed on the tables that are being migrated.
A Direct Connect connection has been established between the CDH cluster and Huawei Cloud Virtual Private Cloud (VPC).

Estimate the amount of data to be migrated and the migration duration.
Output the detailed data tables, the number and sizes of files to be migrated for subsequent verification.
Configure migration tasks in batches to ensure the migration progress and speed.
Check the number and sizes of files.
Restore the HBase table on MRS and verify the restoration.
