I have a SharePoint 2010 application that is nearing the 200 GB limit. I know that I can add another content database. However, my understanding is that I would need to create a site collection in the new content database and have users add new content there. However, there is an established structure in the original content database that users will continue add to (uploading files, creating sub sites, etc).
What is the best procedure to support users adding content to the old stucture?
