9. Migration throughput

    For OneDrive migrations, generally, a reasonable migration speed is 4 GB/hour/mapping. For the number of mappings that can be run, it is automatically allocated based on subscription you purchased. The more user seats you purchase, the more mappings you can run in a project.

    However, OneDrive consists of files and various items/metadata. The data rate may not be the only factor to reflect the migration performance. For example, the content types/other metadata and list items usually take up a small size, but the larger overhead and processing time caused by migration, even the regions of migration, will impact the data rate. Pilot Migration is recommended as the best practice for you to test the actual migration performance. The actual migration performance may vary based on the data complexity.
