Migrate Front50 from S3 to SQL

Hi, Trying to move front50 to SQL and going through this documentation. https://www.spinnaker.io/setup/productionize/persistence/front50-sql/#migration. It does’nt actually document how and where to setup the primary/secondary or the S3StorageService as secondary as per the example.

I already have a S3 Persistant storage setup via hal config. When I simply add the SQL one, it complains that there are multiple accounts and need to either disable one or setup CompositeStorageService with primary/secondary
