Free migration readiness estimator

Nintex to Power Automate migration assessment and ROI calculator

Qualify a Nintex migration before the first workshop. Estimate portfolio complexity, manual rebuild effort, Flow Migrator-assisted effort, Power Platform licensing impact, and potential first-year savings from moving Nintex workflows to Microsoft Power Automate.

Start the assessment Analyze real workflow exports

Size the migration portfolio

Capture workflow counts, active workflows, business-critical processes, average action count, ownership, testing readiness, and inventory quality so teams can separate quick wins from complex remediation work.

Surface migration risk early

Identify patterns that usually drive Power Automate migration effort, including approvals, state machines, child workflows, SQL or API calls, custom task forms, Nintex Tables, XML/XSLT, and on-premises data access.

Build a defensible business case

Compare manual migration cost against tool-assisted migration cost, annual Nintex spend, likely premium licensing, delivery services, and expected request volume before committing to a migration plan.

Interactive questionnaire and ROI model

Create a first-pass Nintex migration business case.

Use this calculator for pre-sales qualification, discovery preparation, and executive planning. It estimates effort from questionnaire inputs; for exact action mappings, blockers, connector requirements, and export readiness, upload real Nintex workflow exports into Flow Migrator.

Migration complexity indicators

Enter the approximate number of workflows that contain each pattern. These signals influence readiness scoring, remediation effort, and migration wave planning.

Approval and task workflowsApproval outcomes, task notifications, reminders, and escalations should be validated before rollout.State machines / stage routingOften maps to stage variables, Do until, and Switch logic in Power Automate.Child and reusable workflowsRequires parent-child dependency mapping and solution packaging review.Database actions and queriesIncludes SQL Server, MySQL, Oracle, PostgreSQL, ODBC/OLEDB, AS400, and gateway-backed sources.HTTP, SOAP, web services, or custom APIsRequires endpoint, authentication, request payload, response schema, and retry behavior review.Custom task forms with value captureMay require Power Apps, a SharePoint task list, or a custom task experience instead of basic Approvals.Nintex Tables dependenciesRequires a replacement data-store decision such as SharePoint Lists, Dataverse, SQL, or an API-backed system.XML, XPath, or XSLT processingXPath may map to expressions; XSLT and complex transforms usually need remediation.On-premises data or gateway accessRequires gateway readiness, credentials, drivers, firewall, and environment checks.Custom code, script, or unsupported extensionsDeveloper review is usually required to convert this logic safely.

Cost, licensing, and usage assumptions

Microsoft 365 is already in placeMicrosoft 365 helps with adoption, but premium connectors and high-volume flows may still require additional licensing.Assume Nintex subscription can be retired after migration

Important discovery risks

Validation test cases are missing or incomplete; include additional testing effort in the project plan.
Nintex Tables are present; choose a replacement data store such as SharePoint Lists, Dataverse, SQL, or an API-backed system before converting dependent workflows.
Custom task forms are present; validate whether Power Automate Approvals are sufficient or whether Power Apps, Teams, or a SharePoint task-list pattern is needed.
Database or on-premises access was indicated; review gateway setup, credentials, drivers, connector licensing, and operational ownership.
Custom API or web service calls were indicated; preserve endpoint, authentication, request payload, response schema, and retry expectations for remediation.
Child or reusable workflows were indicated; build a dependency graph before packaging parent and child flows into migration waves.

Recommended migration next steps

Run Flow Migrator on representative Nintex workflow exports to replace questionnaire estimates with actual support, partial, and unsupported action mappings.
Review custom task forms and decide between Power Automate Approvals, SharePoint task lists, Teams/adaptive-card patterns, or Power Apps.
Map parent/child workflow dependencies and decide which child flows should be shared, reused, or intentionally duplicated.
Inventory Nintex Tables, identify dependent workflows, and select target data stores before converting those workflows.
Group workflows into simple, medium, complex, and remediation-heavy migration waves.

This calculator is a planning tool. Use real Nintex workflow exports in Flow Migrator before finalizing scope, pricing, licensing, or deployment commitments.

Best next step

Move from estimate to evidence.

The questionnaire is designed to start the conversation. Flow Migrator can then analyze exported Nintex workflows to produce supported, partial, and unsupported action counts; Power Automate limit-risk checks; premium connector and gateway flags; and importable Power Automate packages where mappings are supportable.
