Abstract

The National Science Foundation’s Daniel K. Inouye Solar Telescope (DKIST) is a 4-meter solar observatory in operation at Haleakalā, Hawaii. The High-Level Software (HLS) group develops and maintains software and control systems for the observatory. During the nearly 20 yearlong observatory construction phase we utilized the Concurrent Versioning System (CVS) as the revision control component of our software configuration management process. As we transitioned into the observatory operations phase, we began looking at using a more modern revision control system that would offer more flexibility and control for software development going forward. Through our long-term planning process, the decision was made to transition from CVS to the Git revision control system. In this paper we describe the motivation to move from CVS to Git for software revision control at DKIST and explain the planning involved to ensure a smooth transition. We will review challenges faced, planning steps involved, migration results, and look at lessons learned from the process. We conclude by sharing initial feedback from the team on the experience thus far using Git.
