If you need to move a large volume of data, you can do so using an Amazon Web Services ( AWS ) S3 bucket. DME uses AWS for high performance transfer of large files.

To prepare an S3 bucket:

...

In AWS, create a bucket, create an access policy, create an IAM user, get access keys for that user, and set up permissions for the bucket, as described in AWS user documentation:
 https://docs.aws.amazon.com/s3/ 

...

• The name of the destination S3 bucket
• The path to and the name of the file or folder to be created in the destination bucket 
• The access key and secret key
• The S3 region

For instructions on locating this information, refer to AWS user documentation. 

...

. If you intend to use an S3 bucket with the DME CLU,

...

prepare as follows:

1. Use a command line editor (such as vi editor) to create a file with the filename credentials that specifies S3 credential information, as follows:

   Code Block
   [default] aws_access_key_id = <access key> aws_secret_access_key = <secret access key> region = <s3 region>

2. Consider placing the credentials file in the default location for CLU commands, as follows:

   code
