How do I migrate Rails 6 ActiveStorage files from Droplet to Spaces?
My current Rails 6 application is using ActiveStorage to upload and serve files from DO Droplet.
I now want to point the ActiveStorage from local to DO Spaces.
I have acquired the Access Key and Secret for DO Spaces.
I know how to make changes to storage.yml and production.rb files to point the Rails application to DO Spaces, so that future uploads and file access can happen via DO Spaces.
But how do I do a one-time migration of the existing files in my application from local droplet to Spaces?
