RFP Software Migration Timeline: Realistic Expectations (2026)
Timeline by scope
| Phase | Boutique (≤30 events/yr) | Mid-Market (30–100) | Enterprise (100+) |
|---|---|---|---|
| Planning | 3 days | 1–2 weeks | 2–4 weeks |
| Data prep | 2–3 days | 1–2 weeks | 2–4 weeks |
| Import & config | 1 day | 2–5 days | 1–2 weeks |
| Training | 1 day | 2–3 days | 1–2 weeks |
| Parallel-run | 1–2 weeks | 2–4 weeks | 4–8 weeks |
| Post-cutover validation | 1 week | 2 weeks | 4 weeks |
| Total | 2–4 weeks | 6–12 weeks | 12–24 weeks |
Where time is most often lost
Quick answer (40–60 words): Three phases most commonly overrun: (1) data cleaning (legacy data is messier than expected), (2) parallel-run (gaps surface, requiring config tweaks), (3) post-cutover integrations (CRM/accounting tools often need re-mapping). Build 15–25% contingency. The fastest migrations are ones where the team commits to data hygiene before signing the new contract.
Phase-by-phase pro tips
Planning: Get internal alignment first. Migrations stall when stakeholders weren't consulted up front.
Data prep: Don't migrate stale data. Cleaning before import is faster than cleaning after.
Training: Don't skip. 80% of post-migration friction is "user wasn't trained on this thing."
Parallel-run: Don't shorten. The full event cycle is the validation.
Post-cutover: Plan a 30-day retrospective. Capture lessons.
FAQ
Q: Can a boutique migration be done in a week? A: Sometimes — for very simple datasets and small teams. We don't recommend it; you skip parallel-run.
Q: Can enterprise migration be faster than 12 weeks? A: Possible if dedicated resources are committed and scope is clean. Usually it's not.
Q: What's the longest migration we've seen? A: Enterprise multi-region with custom integrations: ~9 months end-to-end. Most enterprise: 4–6 months.
