step by step guide how to restore a dynamodb table into an existing stack. Example after refactoring the cdk code structure.

Restore dynamodb table with cdk.md

Restore DynamoDB in cdk

1. create a backup of the old table

aws dynamodb create-backup --table-name <old-table-name> --backup-name <some-backup-name>

and remember the arn of the backup -> BACKUP_ARN

2. deploy the cdk app with the new target table. This table will be empty.

cdk deploy

3. get the table name of the target table -> TARGET_TABLE
4. delete the target table

aws dynamodb delete-table --table-name <TARGET_TABLE>

5. restore the table backup

aws dynamodb restore-table-from-backup \                                                                           
    --target-table-name <TARGET_TABLE> \
    --backup-arn <BACKUP_ARN>

6. wait until database is restored
7. (optional) run cloudformation drift detection or cdk diff to make sure everythin is up-to-data

Works like a charm, thank you very much! ⭐
