ERP Migration: How It Works, Why It Fails, and the Method That Makes It Reversible
An ERP migration is the most feared project in finance, and most of that fear comes from not knowing how the move actually goes. We have taken the process apart: the sequence, the gates, the parallel run that keeps it reversible, and the reasons migrations fail. We share it here so the decision rests on knowledge rather than on hope: what happens in what order, what can stop the project, and what makes the switch safe.

FAQ
Who is this cluster written for?
Controllers who would run a migration day to day, weighing timeline and risk before it becomes a funding conversation.
What does this cluster cover?
The parallel-run method itself, what changes for a multi-entity structure or a private-equity portfolio standardizing several companies at once, the compliance and IT-authorization questions a security team asks, and the practitioner checklist and business case that carry a migration from first audit to rollback criteria.
What's the single riskiest part of an ERP migration to cut?
Skipping or shortening the parallel run. It is the one phase that generates proof the new system reconciles against the old, and cutting it does not remove that risk. It just moves the discovery of a mismatch past the point where fixing it is easy.
Is fiscal year-end a good time to run the migration?
No. The close already pushes both the team and the ledger to their limit, and layering a second reconciliation on top of that workload for reasons unrelated to closing the books is the wrong week to pick.
What's a realistic ERP migration timeline?
A quarter is the number del.ai scopes and contracts to for a mid-market move off a single-tenant cloud ERP. Audit and build fill the first half, the parallel run the second. Compress or drop that second half and the project can look faster on a slide, but the reconciliation work it would have caught doesn't disappear, it resurfaces after cutover where it is costlier to unwind. del.ai has completed no customer migration, so this is the scoped target, not an observed track record.
