+# Plaintext DynamoDB Table to AWS Database Encryption SDK Encrypted Table Migration
+
+This projects demonstrates the steps necessary
+to migrate to the AWS Database Encryption SDK for DynamoDb
+from a plaintext database.
+
+[Step 0](plaintext/step0.go) demonstrates the starting state for your system.
+
+## Step 1
+
+In Step 1, you update your system to do the following:
+
+- continue to read plaintext items
+- continue to write plaintext items
+- prepare to read encrypted items
+
+When you deploy changes in Step 1,
+you should not expect any behavior change in your system,
+and your dataset still consists of plaintext data.
+
+You must ensure that the changes in Step 1 make it to all your readers before you proceed to Step 2.
+
+## Step 2
+
+In Step 2, you update your system to do the following:
+
+- continue to read plaintext items
+- start writing encrypted items
+- continue to read encrypted items
+
+When you deploy changes in Step 2,
+you are introducing encrypted items to your system,
+and must make sure that all your readers are updated with the changes from Step 1.
+
+Before you move onto the next step, you will need to encrypt all plaintext items in your dataset.
+Once you have completed this step,
+while new items are being encrypted using the new format and will be authenticated on read,
+your system will still accept reading plaintext, unauthenticated items.
+In order to complete migration to a system where you always authenticate your items,
+you should prioritize moving on to Step 3.
+
+## Step 3
+
+Once all old items are encrypted,
+update your system to do the following:
+
+- continue to write encrypted items
+- continue to read encrypted items
+- do not accept reading plaintext items
+
+Once you have deployed these changes to your system, you have completed migration.
