How to Estimate Data Transfer Time for a Cloud Migration

A transfer estimate based only on nominal link speed ignores protocol overhead, concurrency, file count, and changing source data.

Checks to make

Measure sustained throughput with representative data, account for small-file overhead and encryption, and calculate the initial copy plus ongoing change rate. Test restart behavior and checksum validation, then schedule cutover with time for final sync.
