What's the fastest method for migrating 10 TB+ of OneDrive content?

[sanjay210]

For migrations involving more than 10 TB of OneDrive data, speed depends on several factors, including internet bandwidth, file count, file sizes, Microsoft service limits, and migration strategy. In most enterprise environments, the fastest approach is not necessarily moving everything at maximum speed but reducing the amount of data that needs to be transferred and optimizing the migration workflow.

The SysInfo Tenant to Tenant Migration Tool helps by supporting batch processing, incremental migration, and OneDrive data filtering. Organizations often begin by scanning their OneDrive environment to identify duplicate, outdated, or unnecessary files. After cleanup, the migration is typically performed in phases, with multiple user accounts processed simultaneously. Once the initial transfer is complete, incremental migration ensures that only new or modified files are copied during subsequent runs. This approach reduces the final migration window and allows users to continue working while most of the data is already available in the destination tenant.
