Does SMS Support Resumable Data Transfer?

Yes. Data transfer can be resumed if:

• The transfer is interrupted because the source server is disconnected from SMS due to network problems or other reasons. In this case, you do not need to worry about data loss or migration failure. All you need to do is restore the connection and restart the migration using the Start button on the SMS console. For details about how to restore the connection, see How Do I Restore the Connection Between the Agent and SMS?
• You are performing a Linux file-level migration, but the transfer is interrupted because the source server is disconnected from SMS after the Agent or the source server is restarted. You need to click Start on the SMS console to continue the unfinished migration task. If you are performing a Windows or Linux block-level migration, the data transfer cannot be resumed, and you need to delete the migration task and create a new one to migrate all data again.
