Migrating data - When is enough enough

Hello

Is there a rule of thumb people use to statistically ensure data wasn’t corrupted? here’s the scenario: we’re migrating data from one system to another. although the system generates a report saying the migration was successful, QA still wants to audit a representative sample. so what is an acceptable sample size??..i’ve heard people say 0.0015% of the total size.

Any thought?

Thanks

Hi

I’ve used Mil-Std 105e in the past for this specific purpose. Here’s an
online calculator.
