My company is considering migrating to Jenkins for their build, package, and deployment. We are currently assessing the migration cost and would love to get the community’s thoughts on two questions.
What is the approximate number of resources (e.g., x developers) and time (# days at x% utilization) required for a successful migration of about 2500 users from Travis, Github actions, Docker etc. (1400+ users from travis, 100+ users from Github actions, 980+ from others e.g., Docker, Bamboo, ArgoCD etc.)
How long might it take my developers to get fully productive on the tool considering training and ramp up time.
