Migrating to Argo CD can present challenges, especially for teams moving from manual or CI-driven deployments. The most common issues include restructuring repositories to fit GitOps principles, handling legacy YAML files, and managing secrets securely. Teams also need to adapt to Argo CD’s declarative model, which may feel restrictive at first. Ensuring consistent cluster permissions and access control can be another hurdle. However, once the initial setup is complete, the long-term benefits—like automated rollbacks, version tracking, and reduced errors—far outweigh the setup effort. Careful planning and a gradual rollout strategy make migration much smoother.
