Deployment on existing project

Hello guys,

Im new to sage and working on an existing sage 9 project.
I have few questions:

  • Is the the deployment (ftp) process the same as for new projects ?
  • Should I clone my theme folder before compiling assets for production ?
  • What will change if I want to work again on this project ?
  • What is the right workflow for deploying existing projects ?

Thank you and stay safe
