Thank you for the information on Trellis and your experience with it! I’m sure this will be helpful to someone else in the future.
Our forum here is specifically for DevKinsta and it as a local environment.
We do have a blog post here that applies to our live and staging environments.
If you would like, add a comment there and have a look in case you run into other questions about that type of deployment such as adding our MU plugin for your site.
