Validate the migration

To verify that the migration is successful, use the Statistics page in Atlas to compare the metadata in Navigator.

In general, you must verify the following:

• Count of migrated entities. Does the total number of imported entities match what you expect from Navigator? Note that not all Navigator entities are not migrated: HDFS entities are only migrated if they are referenced in Hive, Impala, or Spark operations that are included in the migration cycle.

• Count of managed metadata that became business metadata in Atlas.

• Count of managed metadata assignments. Consider reproducing searches on commonly used business metadata to validate that you see the same results in each system.
