In questa pagina confermi che il job di migrazione ha eseguito correttamente la migrazione dei dati dall'istanza del database di origine all'istanza del database Cloud SQL di destinazione.
Verifica almeno che l'istanza del database e le relative tabelle esistano nell'istanza Cloud SQL. Puoi anche verificare il numero di righe o i contenuti esatti delle tabelle.

You can also verify the tables' row counts or exact\ncontents.\n\n\nThe following steps show a minimal example:\n\n1. Go to the [SQL Instances page](https://console.cloud.google.com/sql) in the Google Cloud console.\n2. Click the read replica entry of your migration job.\n3. Click the **Activate Cloud Shell** icon that appears in the upper-right region of the page.\n4. At the Cloud Shell prompt, press **Enter**.\n5. Optional: If an **Authorize Cloud Shell** dialog box appears, then click **Authorize**.\n6. At the **Enter password** prompt, enter the password that you either provided or that Database Migration Service generated for you in [Define and create the destination Cloud SQL instance](/database-migration/docs/mysql/create-migration-job#dest).\n7. Run SQL commands to verify the migration. For example:\n 1. At the **mysql** prompt, enter `show databases;` to list the databases and verify that you see your source database instance.\n 2. At the **mysql** prompt, enter `use `\u003cvar translate=\"no\"\u003esource_database_instance_name\u003c/var\u003e`;` because you want to see the tables associated with this database instance.\n 3. At the **mysql** prompt, enter `show tables;` to see the tables of this instance.\n 4. At the **mysql** prompt, enter `select * from `\u003cvar translate=\"no\"\u003etable_name\u003c/var\u003e`;` to see the information that's contained in a table of your source database instance.\n 5. Verify that you see the correct information in the table.\n\n\u003cbr /\u003e\n\n\u003cbr /\u003e\n\nIf everything you check is as you expect, then Database Migration Service has migrated the data correctly."]]
