title: Deploy multiple databases with SSDT
body: <p>We have an existing system with multiple databases on one SQL Server instance, and we want to deploy database changes using SQL Server Data Tools. Thus I've created a solution with one database project per database. </p>
  
  <p>When I run a build, it creates a <code>.dacpac</code> file for each project. Ideally we want to bundle the deployment of database changes, such that all databases are deployed in one shot. I've seen that database projects can reference other projects and suppose that you can use this mechanism for bundling as well - but I am reluctant to add references just for the sake of deployment. </p>
  
  <p>What is the recommended way to deploy multiple databases in one package?</p>
