Can anybody help me in this topic related query?
As Brian mentioned, you could try the AWS Database Migration Service. The storage limit with RDS for Oracle is 64TiB. While you are technically below the database storage limit, this will likely be a very challenging project due to the large 50 TB database size.
Supported Sources/Targets for AWS Database Migration Service:

Have you tried the Database Migration Service? It should be pretty simple going from Oracle to Oracle RDS.
