Successful deployment of migration approach for critical business system.

We have managed to design and deploy the migration approach for critical business system with more than 20 TB data from on-premise to public cloud.

We combine two migration technics: Oracle data guard and Snowball service from AWS. This approach helps us to transfer simultaneously mission-critical business systems within 1,5 days as a maximum downtime for migration. This migration approach displays how to combine different migration procedures with minimum downtime for end users.
