Question

Hi fam,

I need to know what is the best and fast way to add encryption to pre create database clusters. that db's are running and i need to add encryption to them because the creation time encryption was not added.

Accepted Answer

hi, Lay

First, You can't convert an unencrypted DB cluster to an encrypted one. 
You can check the detail on the document (https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/Overview.Encryption.html).

Also, you can't use blue/green deployment to convert cluster from unencrypted to encrypt.
https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/blue-green-deployments-overview.html#blue-green-deployments-limitations-general

But, you can restore a new cluster from unencrypted snapshot.
