- Verify and make-up the DB accounts in the restored TiDB Cluster, while the DB account from the primary TiDB Cluster will not be restored  with the TiDB version earlier than **6.2.x**..
- Verify and make-up the SQL Binding from the primary TiDB Cluster, which is not restored and replicated  with the TiDB version earlier than **6.2.x**..
- Verify that all the schemas are identical between two TiDB Clusters if no DDL happens after the restore operation, such as databases, tables, indexes and etc.
- Verify that the replication is working in the restored TiDB Cluster, including both DMLs and DDLs. All data should be identical with the primary TiDB Cluster.
- Verify that all global variables are identical between the two TiDB Clusters. If not, fetch the value from the primary and set it to the restored TiDB Cluster.
- Verify and make-up the statistical data for Optimizer in TiDB, i.e., rebuild the system table mysql.stat_* for Optimizer to make good plan for queries.
- Verify and make-up the auto-incremental cache in the restored TiDB Cluster, which will be conflict with what is replicated from the primary TiDB Cluster.
- Verify and make-up the placement rule in the restored TiDB Cluster.
