Their deployment UI looks nice but this feels like they made their own wheel here in order to keep their In-place upgrade method over something such immutable infrastructure using pre-existing deployment systems.

I wonder if this was ruled out for some reason or perhaps for a large company with people dedicated to deploying this doesn't matter. One example, as they are on AWS autoscaling groups with prebuilt AMI's could have been used to roll new machines instead of copying files to the server.
