About this tool
Enter the amount of data, the link speed and how much of the link you can realistically use. The result is the copy time and the amount that fits in a typical change window. It is a planning estimate for file server, OneDrive, SharePoint and datastore migrations; real throughput depends on file counts, latency, throttling and the tool used.
