The RSA Archer Migration Checklist
Seven phases from pre-decision to decommission, with realistic timelines for a mid-market instance. Archer migrations fail in the phases teams skip — usually the data audit. Work it in order.
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 weeksPhase 2 — Data Audit
2–6 weeks (longer if your Archer admin has departed)Phase 3 — Platform Selection
3–6 weeksPhase 4 — Extraction
2–5 weeks, sized by the data auditPhase 5 — Validation
1–3 weeks, overlapping extractionPhase 6 — Cutover
4–10 weeks depending on program sizePhase 7 — Decommission
2–4 weeks, gated on a clean cycleDeeper material for the heaviest phases: the Archer data export guide covers Phase 4's mechanics in practitioner detail, the alternatives guide and Archer vs Vanta comparison cover Phase 3's category question, and the full Archer to Vanta migration guide walks the cutover step by step.
