Migrating a DynamoDB table from one account to another
You can migrate an Amazon DynamoDB table from one account to another to implement a multi-account strategy or a backup strategy. You can also do it for testing, debugging, or compliance reasons. A common use case is copying DynamoDB tables across production, staging, test, and development environments where each environment utilizes a different AWS account.
DynamoDB offers two options for migrating tables from one AWS account to another:
-
AWS Backup for Cross-Account Backup and Restore: AWS Backup is a fully managed backup service that enables you to centrally manage backups across multiple AWS services. With its cross-account backup and restore functionality, you can back up a DynamoDB table in one account and restore the backup to another account in the same AWS Organization.
-
DynamoDB Export and Import to Amazon S3: Using the DynamoDB Export and Import to Amazon S3 features allows you to do a full export to an Amazon S3 bucket and then import that data into a new table in another AWS account. This approach is suitable when you need to migrate between accounts that are not part of the same AWS Organization or if you do not want to use AWS Backup.
Note
Import from Amazon S3 does not support tables with Local Secondary Indexes (LSIs), but it does support Global Secondary Indexes (GSIs). For more information on LSIs and GSIs, see Improving data access with secondary indexes.
