Does SMS Support Resumable Data Transfer?

Yes. If a migration is interrupted before it completes due to network problems or other reasons, SMS can retry the transmission and pick you up where you left off. All you need to do is rectify the problem and restart the migration using the Start option on the SMS console. Please note that the Agent or source server cannot be restarted during a Windows migration. This is because the address for accessing the incremental data is stored in the memory. If the Agent or source server is restarted, incremental data cannot be synchronized.
