Migration Guide Documentation

Migration guide documentation provides step-by-step instructions for upgrading between design system versions. These guides address breaking changes, deprecated patterns, and new approaches that users must adopt. Effective migration guides significantly reduce upgrade friction and support burden.

What Is Migration Guide Documentation

Migration guide documentation is instructional content that helps users move from one design system version to another. Unlike changelogs that list what changed, migration guides explain what users must do to adapt their code. Guides focus on breaking changes and required actions rather than comprehensive change lists.

Migration guides bridge the gap between announcing changes and successfully implementing them. They translate abstract change descriptions into concrete code modifications. Good migration guides anticipate common questions and pain points, addressing them proactively.

How Migration Guide Documentation Works

Migration guides organize around breaking changes, with each change receiving dedicated coverage. Coverage includes explanation of what changed and why, code examples showing before and after patterns, step-by-step instructions for making the change, and common pitfalls or edge cases to watch for.

Guides typically progress from simple, widespread changes to complex or rare cases. This ordering helps users tackle quick wins first while building understanding for harder migrations. Estimated effort or impact ratings help users plan migration work.

Some migration guides include or reference automated migration tools. Codemods can transform code patterns automatically, handling straightforward migrations. Guides explain what codemods handle and what requires manual attention. This combination of automation and documentation accelerates migration while ensuring thorough coverage.

Key Considerations

• Each breaking change should have dedicated coverage with before and after examples
• Instructions should be specific and actionable rather than general guidance
• Automated migration tools complement documentation by handling mechanical transformations
• Estimated effort ratings help teams plan migration timelines

Common Questions

When should migration guides be created relative to releases?

Migration guides should be substantially complete before releases ship, not after. Users encountering breaking changes without guidance creates support burden and frustration. Draft guides can develop alongside breaking change implementation, ensuring changes are actually migrateable. Guide refinement may continue post-release based on user feedback, but initial guidance must exist at release time.

How do teams handle migrations that cannot be automated?

Some migrations require judgment calls or context that automation cannot handle. Migration guides should identify these cases clearly, explaining what decisions users must make and providing guidance for common scenarios. Patterns that require manual migration warrant more detailed documentation than automatable changes. Support channels should prepare for questions about complex migrations. Some teams offer office hours or direct support during major version transitions.

Summary

Migration guide documentation provides actionable instructions for upgrading between design system versions. Effective guides cover each breaking change with examples and step-by-step instructions. Combining documentation with automated migration tools accelerates adoption while ensuring users successfully navigate complex changes.
