Hi, once we launch our site and realize that our server's storage is being consumed rapidly with Photos by the users being posted either on their profile or conversations, is it possible to switch to Amazon S3 while we have several files already on our server or this needs to be setup before launching our site? Is there a way to reduce the size of photos at a minimum? Is there advantage or disadvantage opting to store the files to S3 as offered within EasySocial?
