After the classic Sales (ADF) to Redwood migration is completed on Development, how do I promote it from Dev to Test?

You can deploy the changes from your Development to Test environments through a build job in Visual Builder (VB). You can add your Test or Production environment and migrate the changes from your VB project to higher environments.

You'll need to do a CSM from Development before the deployment to sync all model layer changes that you have with the VB project.

Important: For Test to Prod migration, move Application Composer and UI changes first and then do the VB migration separately.
