Atlassian is retiring Bamboo Data Center, with full end of life on March 28, 2029. Teams using Bamboo should start planning their migration now, beginning with an audit of existing pipelines rather than jumping straight to tool comparisons. The key advice is to avoid migrating technical debt — use the transition as an opportunity to rebuild and simplify CI/CD workflows. A real-world example from Keylane shows how rebuilding from scratch with TeamCity's Kotlin DSL reduced a 1-hour build to 6 minutes. Common replacement options covered include Bitbucket Pipelines, GitHub Actions, GitLab CI/CD, Jenkins, and TeamCity, each with different trade-offs around hosting, scalability, and ecosystem fit. The recommended migration approach is phased and iterative, running old and new systems in parallel rather than doing a hard cutover.
