Convex Migration Helper
Use this when a schema change affects existing rows or when data shape must be transformed.
Migration defaults
- Prefer additive changes first.
- Add required fields as optional, backfill, then tighten.
- Use internal functions for migration work.
- Keep the app running during the migration whenever possible.
When this skill is needed
- Required fields are being introduced.
- Field types are changing.
- Nested data is being split into relational tables.
- Existing indexes or lookup paths are changing in ways that require backfills.
What to check
- Is a dual-read or dual-write period needed?
- Can the migration run in batches?
- Does the schema need a temporary compatibility state?
- Are there existing functions that assume the old shape?
