How can I move 15TB of legacy email data in PST files to Vaultastic, and how will this impact my cost?

Vaultastic integrates Legacyflo, a scalable migration tool, to seamlessly import large volumes of data, such as 15TB of legacy email in PST files, into the respective vaults on the Active Store or directly into the Open or Deep Store for long term retention. 

For such a large dataset, we may recommend using AWS Snowball or Snowcone, which allows physical transfer of the data to the cloud, speeding up the migration process. 

To manage costs efficiently, Vaultastic deploys storage tiering. This approach keeps recent, frequently accessed data in the Active store while moving older, infrequently used data to the cost-optimized Open Store, potentially reducing long-term storage costs by up to 60%.
