V1 [UX4] Migration story

[austin-barrington]

Context

Adoption often requires moving from InfluxDB 1.x or another backend. Without guidance, evals stall.

Deliverables

• Document recommended migration patterns (dual-write window, historical backfill, measurement-by-measurement).
• Tooling pointers (export formats, rate limits) and known query dialect gaps.
• Security note for bridge credentials during migration.
