dependency-upgrade

Major dependency upgrades carry breaking-change risk. Perform compatibility analysis first—identify API changes, deprecations, and migration paths. Test incrementally across unit, integration, and end-to-end suites. Stage rollouts progressively rather than deploying all changes at once. Use semantic versioning guidance to plan which versions are safe intermediates.

Staged upgrade planning reduces breaking-change risk. Analyze compatibility between your current version and the target, generate a compatibility matrix, and identify conflicts early. Plan incremental upgrade paths through intermediate versions if needed. Coordinate testing and rollouts across teams to catch issues before production deployment.

Run automated tests across unit, integration, and end-to-end layers after upgrading. Compatibility verification catches breaking changes before deployment. Document risk areas and migration steps for your team. Combine testing with staged rollouts so failures in one phase don't affect production.

Upgrading multiple dependencies simultaneously compounds risk—conflicts between versions become harder to isolate. Perform compatibility analysis for each upgrade independently first, then test their interactions. If conflicts arise, stage upgrades sequentially or plan incremental paths through compatible intermediate versions.

Document the upgrade plan, compatibility findings, migration steps for breaking changes, and test results. Risk assessment—what could break and how you'll catch it—helps teams understand the upgrade scope. This documentation supports both the upgrade process and future maintenance decisions.

Dependency conflicts often arise from version constraints between packages. Use compatibility analysis to identify which versions work together. Plan incremental upgrade paths through intermediate versions that satisfy all constraints. Test each step to confirm the conflict is resolved before moving forward.
