When you select the 'Do not compare table contents' option during the database migration option (DMO) procedure, the following actions are performed: The clustered tables are declustered, facilitating the transition to the new database structure. Additionally, a row count is executed for the migrated tables to ensure data accuracy in terms of the number of rows, without comparing the actual contents of the rows. Generating a check sum every 10000 rows or content comparison for repository tables would defeat the purpose of opting not to compare table contents.
