How-To Copy DynamoDB Table To Another Account, Table or Region

Whether you want to copy your DyanamoDB table data to another account, table, or region, doing so can be a tedious task. In this step-by-step guide (with screenshots), I'll walk you through how to migrate your DynamoDB table data the easy way.

The traditional way of doing this would be to create a custom pipeline or write your own specific script but since that'll take us a lot of time, I'll be using Dynobase to make our life easier. Dynobase is a desktop-based visual admin tool for DynamoDB that'll make this data migration task a breeze. It's very well suited if you want to manage multiple regions and multiple AWS profiles in a single place which is what we are trying to do in this use case. So let's get started by first downloading the 7-day free trial of Dynobase (no CC required) by clicking here.

Preparation

1. Download Dynobase
2. Setup AWS CLI Profile(s) (skip this step if you've already done it)

Setup AWS CLI Profile(s)

If you've not set up AWS credentials under ~/.aws, you'll see the following screen when you start Dynobase.

To have your credentials setup, follow the steps below:

Step #1 - Set Up New IAM User

Part 1 - Get the credentials from the web console by creating an IAM user.

Part 2 - Select a name and tick the checkbox to confirm you want to create credentials to get programmatic access.

Part 3 - Type DynamoDB in the input and select AmazonDynamoDBFullAccess. This will give us enough permission to do our task but beware of what permission you give other users in the organization for safety and security purposes.

Part 4 (optional) - If you want to tag your users, you can fill in the details, but I've personally left it empty.

Part 5 - Hit the review button and then create the user. You'll be shown the credentials.

Step #2 (final step) - Configure AWS Profiles via CLI

Part 1/2 - Setting Up 1st Account - We'll need to use aws cli to configure the credentials as shown below by using the command aws configure, which will create a default user.

Part 2/2 - Setting Up 2nd Account (only relevant if you'd like to transfer table to another account) - To migrate your DynamoDB table to another account, you'll need to gather credentials from the second account and create another profile with aws cli with the following command - aws configure –profile 2nd-account - Here, 2nd-account reflects the name of the profile, and it can be anything as you like. For more information on setting up multiple AWS profiles, please see this article.

Transfer DynamoDB Table to Another Account

Step #1 - Open Dynobase

Step #2 - Export Table Data

Part 1 - To begin the data migration, we'll first need to import the table locally on our PC. Click on the Export button in the bottom-right corner.

Part 2 - Select Whole Table.

Part 3 - Select the default option and click on Export Table.

Part 4 - Choose the file location, and the data will be saved in JSON format.

Step #3 - Add 2nd-Account to Dynobase

Part 1 - Now that you've exported the file, let's move on to importing the 2nd-account we created via CLI to Dynobase. Click on the default dropdown above and then choose + Select more profiles . Select your 2nd-account profile in the Included AWS Profile dropdown and then click on Reload profiles.

Part 2 - Again, in the top-left profile dropdown, select our newly added 2nd-account.

Step #4 - Create Table in New Account

Part 1 - Click on the + icon ionn the bottom-left side to create another table.

Part 2 - Enter the table name, and after configuring the Key names exactly the same as the table you exported data from, click on Create Table.

As you can see, we can now see the newly created table here.

Step #5 (Final Step) - Import Data to Table in New Account

In the bottom-right, click on the Import button - after which you'll see the following wizard:

Click on Import records to initiate the import process. This process will take some time, depending on how large the file is.

And there you have it, all the items were successfully imported to another table with the exact count of 96,208 items as shown below.

As a security measure, do delete the IAM user create above via the AWS console once you're done with this.

Transfer DynamoDB Table to Another Region

Step #1 - Open Dynobase

Assuming you've already configured your IAM credentials, you should be able to see all the tables on your account like below.

Part 1 - Click on the + icon on the bottom-left side to create another table.

Part 2 - Give your table a name, configure the Key names exactly as the original table and make sure to select the right region where you want to upload all the data. Finally, click on Create Table.

As you can see, the created table is being reflected here.

Step #4 (Final Step) - Import Data to Table in New Region

Part 1 - In the bottom-right, click on the Import button - after which you'll see the following wizard:

Click on Import records to initiate the import process. This process will take some time, depending on how large the file is.
