DC products introduce two tracks: Continuous and Classic. You need to decide which track to be on prior to deployment as they are quite different. See Document Cloud Product Tracks — Enterprise Administration Guide
- The Classic track is "business as usual" (like 11). Use a license to preserialize the installer.
- The Continuous track can use a license, but it also can be activated by user ID for admins who want to use named-user deployments and manage entitlements via the Enterprise Dashboard.
Hope that gets you started.
