Frequently Asked Questions
- What Python versions does the Upgrade Planner support?
- The Upgrade Planner supports Python versions from 2.7 through 3.13 and beyond. It covers all major and minor releases, including end-of-life versions, to help you plan migrations from legacy codebases.
- How is upgrade risk calculated?
- Risk scores are based on several factors: EOL status of the source version, remaining support window, number of version hops required, and known breaking changes between versions. Larger jumps and migrations from unsupported versions carry higher risk.
