Salesforce Marketing Cloud Next Deployment

I’m currently working on Salesforce Marketing Cloud Next in a sandbox environment and I’m trying to understand the best approach for moving the entire setup and configuration to a UAT environment. 

My questions are:

• Can this be automated using VS Code + Salesforce CLI / metadata deployment?

• Which types of configurations and assets can be migrated automatically, and which ones need to be recreated manually?

• Are there any best practices for promoting configurations from sandbox → UAT → production in Marketing Cloud Next?

I’d also love to hear how you approached this in real projects and what tools or processes you used for deployment and version control.

Thanks!
