What are the phases of an RSA Archer migration?

Seven, in order: pre-decision, data audit, platform selection, extraction, validation, cutover, and decommission - 37 items in total, with realistic timelines per phase for a mid-market instance. Archer migrations fail in the phases teams skip, usually the data audit, so work the list in sequence.

Phase 1 - Pre-Decision

2–4 weeks

Phase 2 - Data Audit

2–6 weeks (longer if your Archer admin has departed)

Phase 3 - Platform Selection

3–6 weeks

Phase 4 - Extraction

2–5 weeks, sized by the data audit

Phase 5 - Validation

1–3 weeks, overlapping extraction

Phase 6 - Cutover

4–10 weeks depending on program size

Phase 7 - Decommission

2–4 weeks, gated on a clean cycle

Deeper material for the heaviest phases: the Archer data export guide covers Phase 4's mechanics in practitioner detail; the alternatives guide, the Archer vs Vanta and Archer vs Drata comparisons, and ZenGRC vs Archer cover Phase 3's destination question; and the full migration guides - Archer to Vanta and Archer to Drata - walk the cutover step by step. For a personalized complexity score before you start, take the legacy migration assessment.
