#9. Migration throughput

For SharePoint Online migrations, generally, a reasonable migration speed is 2 GB/hour/mapping. For the number of mappings that can be run, it is automatically allocated based on the subscription you purchased. The more user seats you purchase, the more mappings you can run in a project.

However, SharePoint Online consists of files and various items/metadata/settings. The data rate may not be the only factor to reflect the migration performance. For example, the site features/content types/other metadata/settings 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.
