# Migration overview

This section summarizes common migration paths with an emphasis on determinism
and auditability. Detailed steps live in the source migration docs.

Key migrations
- No-merge migration to Link-Not-Merge (LNM) observations and linksets.
- Enable reachability signals and graph parity.
- Policy parity and exception governance alignment.
- CycloneDX 1.6 to 1.7 data model transitions.

Common principles
- Use feature flags and shadow modes before cutover.
- Record deterministic backfill outputs and checksum reports.
- Verify parity with golden corpora and CI tests.
