Amazon S3 Storage Adapter Help

I’m looking to implement the S3 storage adapter to my Digital Ocean install of Ghost using GitHub - colinmeinke/ghost-storage-adapter-s3: An AWS S3 storage adapter for Ghost

What I don’t understand is:

  • What happens to all my existing images located in /var/www/ghost/content/images/. Are they used anymore once the adapter is activated?
  • Once I’ve setup a bucket, do I copy over all my existing images?
  • Once adapter is activated, will images be uploaded to ghost AND S3?

Sorry if these are stupid questions…
