Troubleshoot data migration
Rows from my Stretch-enabled table are not being migrated to Azure. What's the problem?
There are several problems that can affect migration. Check the following things.
Check network connectivity for the SQL Server computer.
Check that the Azure firewall is not blocking your SQL Server from connecting to the remote endpoint.
Check the dynamic management view sys.dm_db_rda_migration_status for the status of the latest batch. If an error has occurred, check the error_number, error_state, and error_severity values for the batch.
The Azure firewall is blocking connections from my local server.
You may have to add a rule in the Azure firewall settings of the Azure server to let SQL Server communicate with the remote Azure server.
