Migrate on Premise Oracle DB of size 8TB to AWS RDS Oracle

Customer has an Oracle 11g running on 2 nodes RAC on premise. The size the DB is 8TB. I need to migrate the Oracle DB from on premise to AWS RDS Oracle.

I shall use Data Pump and AWS DMS with CDC. Customer has a requirement of zero or near zero downtime during migration.

But how can I take the backup of 8TB to S3 from on premise and download it from S3 to AWS? S3 has a limitation on file size of 5TB.

Please help.

This can be achieved by using AWS snowball edge Devices

Larger data migrations can include many terabytes of information. This process can be cumbersome due to network bandwidth limits or just the sheer amount of data. AWS Database Migration Service (AWS DMS) can use Snowball Edge and Amazon S3 to migrate large databases more quickly than by other methods.
