The method, in full

From an unknown estate to a proven switch

Seven stages, each producing a concrete artefact and a decision gate. This is the sequence a fixed-price migration actually runs through — from the first guided estimate to a stabilized, operated system.

One controlled route

Seven stages, seven decision gates

Assess, Map, Price, Port, Prove, Switch, Operate. Each stage below opens onto what it actually produces — not just a name on a rail.

What each stage actually produces

The method, stage by stage

01 · Assess

Assess

Capture the estate and the business reason for moving. The quick estimate is guided and self-reported; verification — or a paid Blueprint — captures the real structural inventory next.

  • A structural inventory draft: active, paused, duplicate and ownerless workflows
  • The stated business driver and initial criticality flags
  • Six readiness dimensions: inventory completeness, mapping confidence, operational criticality, test readiness, security & access readiness, cutover complexity

Decision gate — is there enough evidence to classify mappings and quote scope, or does a Blueprint need to resolve material unknowns first?

02 · Map

Map

Classify every in-scope component — Direct, Transform, Rebuild, Retire or Resolve. Not every workflow is worth rebuilding, and not every mapping is one-to-one.

  • A mapping table per workflow or pattern, with classification and required proof
  • A rationalization list — what merges, retires, or is replaced by a native feature
  • Flagged “Resolve” items that cannot yet be classified

Decision gate — do unresolved items exceed the materiality threshold? If so, they must be resolved — typically through a Blueprint — before scope can be quoted.

03 · Price

Price

Resolve the material unknowns and lock a fixed quote against a versioned scope manifest — not a rough conversation.

  • A locked scope manifest: amount, version, validity date, assumptions, exclusions, payment stages, acceptance summary, named reviewer and customer acceptance

Decision gate — does the verified scope fit inside a published package's caps — workflow count, complexity, critical-workflow count, custom code, environments? If not, it becomes a custom fixed quote or a Blueprint.

04 · Port

Port

Build the destination in controlled waves, with documentation and configuration ownership recorded as you go — not a single big-bang rebuild.

  • Rebuilt workflows in the destination platform, organized by wave
  • Build documentation and ownership records for each wave

Decision gate — has each wave passed internal review before it moves into acceptance testing?

05 · Prove

Prove

Run the agreed tests and compare source and target outcomes where feasible. A workflow that “ran once” is not the same as an accepted outcome.

  • An evidence ledger per critical workflow: trigger tests, transformation checks, side-effect reconciliation, retry and failure behaviour, monitoring verification

Decision gate — have all critical acceptance cases passed, or been explicitly waived by the named reviewer? Cutover does not proceed over unresolved failures.

06 · Switch

Switch

Execute a cutover and rollback plan that was written in advance — not improvised on launch day.

  • A cutover record: freeze and redirect steps taken, the go/no-go checklist, rollback trigger conditions

Decision gate — if a rollback trigger fires inside the cutover window, the team reverts to source per the pre-agreed plan.

07 · Operate

Operate

Monitor failures, support recovery and improve the estate through a defined stabilization window — and beyond it, if you choose FlowPorter Managed.

  • A stabilization-window monitoring log and handover documentation
  • Optionally, a FlowPorter Managed service boundary for ongoing operation

Decision gate — has the stabilization window closed without unresolved incidents, and is there a named operating owner going forward?

How confidence is built

Three evidence levels, three kinds of confidence

A fixed price is only as honest as the evidence behind it. FlowPorter names the level explicitly rather than presenting every number with equal confidence.

L1

Guided estimate

Self-reported answers produce a recommendation — Move, Blueprint, Optimise First or Stay — and an indicative price band. Band width reflects stated confidence, never false precision. Directional only; never a binding quote.

L2

Structural verification

FlowPorter confirms the real inventory, a mapping classification per workflow, and the dependency map. Enough to narrow the band and lock a fixed price for straightforward, well-documented estates.

L3

Blueprint

A paid deliverable covering inventory, mapping, architecture, risk register, acceptance plan, cutover plan and a fixed implementation quote. Required whenever complexity, criticality or missing documentation would make a blind quote irresponsible.

The fixed-price lock point

Fixed price, without pretending the unknowns don't exist

A blind quote just transfers hidden risk into change requests or poor delivery later. FlowPorter uses a clearer sequence instead.

01 · Estimate

Directional range

A band from your self-reported answers. Useful for direction, never binding.

02 · Verify

Inventory & evidence

We confirm the structural inventory, mappings, critical workflows and dependencies.

03 · Lock

Scope + acceptance

You approve the scope manifest, acceptance plan and fixed implementation price.

04 · Deliver

Fixed-price move

We absorb normal delivery variance inside the agreed scope.

Scope manifest anatomy

What a locked fixed quote actually shows you

Not a one-line number. A locked quote is attached to a document you can read before you sign.

Scope manifest — anatomy Locked

Nine things a locked quote states plainly

Fixed price
Stated amount
Manifest version
e.g. ZAP-N8N-v1.3
Validity date
Quote expiry
Assumptions
Stated, falsifiable
Exclusions
Named, not implied
Payment stages
Tied to milestones
Acceptance summary
What "done" means
Named reviewer
Accountable approver
Customer acceptance
Signed before Port begins

Illustrative anatomy — actual manifest content and layout vary by project.

Map

Every workflow receives a route classification

Five classifications — not a universal one-to-one promise.

Direct

The target has an equivalent pattern with limited configuration change.

Transform

The outcome is preserved but the workflow structure or field mapping changes.

Rebuild

Custom logic, state, approvals or platform-specific behaviour needs deliberate engineering.

Retire

The workflow is obsolete, duplicated, or better handled by a native feature at the destination.

Resolve

Ownership, behaviour or dependency is unclear and must be verified before it can be quoted.

Prove

Acceptance is an agreed outcome, not a green node

For every critical workflow, FlowPorter agrees what success means before Port begins. Representative inputs and known failure paths are tested, and side effects are reconciled. Where it is safe and practical, source and destination run in parallel before cutover; where parallel operation would risk duplicate payments, messages or records, the Blueprint defines another controlled proof method instead.

Switch

Cutover follows a decision gate, not a single happy path

The route from an estimate to an operated system branches at real decision points — including paths that do not end in a migration at all.

Stay

No migration is priced. You keep the reasoning and the conditions that would change the decision later.

Optimise First

A bounded rationalization pass fixes source hygiene, then the estate is re-estimated.

Blueprint

A paid deliverable resolves the material unknowns and itself produces a fixed quote.

Move → Verify

Structural verification confirms scope for an adequately documented estate.

Blueprint and Verify both converge on the same locked scope manifest.

Fixed Quote Port Prove
Remediate

A failed acceptance case is fixed and re-tested — looping back into Port before cutover is considered again.

Switch

All critical cases pass. Cutover executes against the prepared rollback plan, then Stabilize → Operate.

Shared accountability

Who owns what, stage by stage

FlowPorter owns
  • The verified inventory, mapping and scope manifest
  • Implementation in the destination platform, per the locked scope
  • Acceptance test design and execution for the agreed cases
  • Cutover and rollback planning
  • Documentation and handover materials
  • Stabilization-window monitoring
Customer owns
  • Naming the true business owner for each workflow
  • Providing sample inputs, test data and environment access
  • Approving the scope manifest and acceptance plan
  • Source and destination subscription and licensing decisions
  • Timely decisions during verification and acceptance
  • Operational ownership after stabilization, unless FlowPorter Managed is contracted

Illustrative

An example project timeline

For a mid-sized estate moving through structural verification rather than a full Blueprint. Actual duration depends on verified scope, wave count and how quickly the customer can respond.

Wk 1

Assess & verify

Guided estimate, then structural verification of the inventory and mappings.

Wk 2

Lock scope

Scope manifest, acceptance plan and fixed price reviewed and approved.

Wk 3–5

Port

Rebuild in controlled waves against the approved scope manifest.

Wk 5–6

Prove

Agreed acceptance tests run; any failures are remediated and retested.

Wk 6

Switch & stabilize

Cutover executes against the rollback plan; the stabilization window monitors the estate.

Illustrative timeline only — not a delivery commitment for any specific estate.

Questions, answered

The things people ask about the method

How can FlowPorter offer a fixed price?

We attach the fixed price to a verified scope manifest, not a rough conversation. The assessment identifies the size and complexity of the estate. Structural verification or a paid Blueprint resolves material unknowns, and the acceptance plan defines what completion means. Normal delivery variance inside that approved scope is FlowPorter's responsibility.

Is the online estimate a binding quote?

No. It's an indicative range based on the information you supply. A binding fixed quote follows structural verification and, where required, a paid Blueprint.

Do you automatically convert every workflow?

No. Some patterns map directly, some require transformation or rebuilding, and some should be retired. Our promise is a verified outcome — not a one-click conversion claim.

Can both systems run in parallel?

Often, but not always. Parallel operation can create duplicate side effects for actions such as payments, messages or record creation. The Blueprint defines where shadowing, suppression, test accounts, replay or another proof method is safe.

What happens if the assessment says we should stay?

You receive the reasoning and the conditions that may change the decision later. FlowPorter is designed to support a sound switching decision, not to force every visitor into a project.
