abstract = {{The control systems of large research facilities like synchrotrons are composed of many different hardware and software parts. Deploying and maintaining such systems require proper workflows and tools. MAX IV has been using Ansible to manage and deploy its full control system, both software and infrastructure, for many years with great success. We detail further improvements: defining Tango devices as configuration, and automated deployment of specific packages when tagging Gitlab repos. We have now adopted Conda as our primary packaging tool instead of the Red Hat Package Manager (RPM). This allows us to keep up with the rapidly changing Python ecosystem, while at the same time decoupling Operating System upgrades from the control system software. For better management, we have developed a Prometheus-based tool that reports on the installed versions of each package on each machine. This paper will describe our workflow and discuss the benefits and drawbacks of our approach. }},
