Nintex End of Life 2026: The Complete Migration Guide for SharePoint Users

Two Nintex products. Two deadlines. One pillar guide.

If your organization runs automated workflows on Nintex for Office 365 or Nintex for SharePoint, 2026 is the year both products reach end of life. One deadline has already passed. The other is weeks away. And the common assumption that these are the same event with the same date is one of the reasons many teams are late to their migration.

April 2, 2026. Microsoft retired the SharePoint 2013 Workflow Engine in Microsoft 365 and the SharePoint Add-In model. Nintex for Office 365 workflows stopped running. Nintex Forms for Office 365 stopped opening. This happened. There is no patch, no extension, no workaround.

July 14, 2026. Microsoft ends extended support for SharePoint Server 2016 and SharePoint Server 2019. Nintex for SharePoint, the on-premises product, runs on those Microsoft platforms. When the infrastructure loses support, Nintex for SharePoint loses its supported foundation. Compliance exposure begins immediately.

This pillar guide covers both realities. What ended and what is ending? Who is affected? What breaks, and what keeps running on unsupported ground. The three migration paths that actually work. A side-by-side comparison table. A ten-step migration checklist. And a direct guide to picking the path that fits your environment.

This piece is also the hub for the rest of the campaign. If you are an Nintex for Office 365 customer dealing with the April 2 aftermath, a Nintex for SharePoint customer with a July 14 clock, or a buyer comparing replacement platforms, there are dedicated blogs below this pillar that go deeper on each situation.

What Nintex’s end of life actually means in 2026

End of life in software terms means a vendor stops supporting a product. No bug fixes. No security patches. No technical assistance. In Nintex’s 2026 case, it means more than that, and the difference matters depending on which product you run.

Nintex for Office 365 (ended April 2, 2026)

Nintex for Office 365 was the version that ran inside SharePoint Online as a Microsoft 365 application. It depended on two pieces of Microsoft infrastructure: the SharePoint 2013 Workflow Engine and the SharePoint Add-In model. Microsoft retired both on April 2, 2026.

This is not a soft deadline. The workflows do not run. The forms do not open. The infrastructure they were built on was removed from Microsoft 365. There is no version of Nintex for Office 365 that continues working without that infrastructure. For O365 customers, end of life means the product is no longer executable in the environment it was built for.

Nintex for SharePoint (ends July 14, 2026)

Nintex for SharePoint is the on-premises product. It runs inside SharePoint Server 2010, 2013, 2016, 2019, and Subscription Edition. The most-deployed versions in the enterprise market today are SharePoint Server 2016 and 2019, and both reach Microsoft’s end of extended support on July 14, 2026.

For Nintex for SharePoint customers, the situation is different from the O365 product. The software does not stop running on July 14. It runs on Microsoft infrastructure that is no longer receiving security patches or support. For regulated organizations that require vendor-supported software for production workloads, that position is difficult to defend in an audit.

What is not in scope

The current Nintex products remain available and are not affected by these dates:

• Nintex Automation CE, Nintex’s current cloud-first platform
• Nintex Automation K2, Nintex’s current self-hosted platform, and Nintex’s official recommended path for on-premises customers
• Nintex for Salesforce and other Nintex ecosystem products not tied to SharePoint

If your contract is already on one of these products, the 2026 deadlines do not directly affect you. If you are on the legacy Office 365 or SharePoint products, migration is the only path forward.

The complete 2026 Microsoft and Nintex timeline

Seven retirement dates in 2026 affect Nintex customers either directly or indirectly. Here is the full set, side by side.

Two of these dates are the primary forcing functions. The other five tighten the case for replacing legacy workflow infrastructure now rather than later.

Who is affected?

If your organization runs either of the legacy Nintex products, you are in scope for one of the two deadlines. The table below helps you confirm which one.

The fastest confirmation path is to check your Nintex admin panel for the product version or to contact your Nintex account manager for the specific contract details. Once you know which product you are on, the relevant deadline and migration considerations follow.

The risks of not migrating

Not migrating is not a passive choice. The risks look different depending on which product you are running, so this section covers both.

If you are on Nintex for Office 365: the workflows have already stopped

The O365 product is not a future-tense risk. It is a current-state reality. On April 2, 2026, Microsoft retired the SharePoint 2013 Workflow Engine in Microsoft 365 and the SharePoint Add-In model. Nintex for Office 365 workflows and forms stopped functioning that day. They have not resumed.

Organizations that have not yet put a replacement in place are running without critical automation, managing through manual processes or ad-hoc workarounds. The compliance implications are immediate: if your approval workflows, audit trails, or policy acknowledgments were built on Nintex for Office 365, that documentation is not being generated. For any process that depended on the workflow for legal, regulatory, or audit purposes, the trail is broken.

If you are on Nintex for SharePoint: compliance exposure starts July 14

For on-premises customers, the software keeps running past July 14, 2026. That is the point most teams miss. The risk is not that everything stops. The risk is that everything keeps running on Microsoft infrastructure that is no longer patched, supported, or compliant with the frameworks many organizations are bound by.

• Security vulnerabilities: Software without active Microsoft patching accumulates vulnerabilities. Running business-critical workflows on SharePoint Server 2016 or 2019 after July 14, 2026 exposes your environment and your workflow data to any vulnerability discovered after that date with no fix on the way.
• Compliance and audit risk: Frameworks including HIPAA, FedRAMP, CMMC, PCI DSS, and SOC 2 require vendor-supported software for regulated workloads. An unsupported SharePoint environment running business process automation creates explicit audit findings. Legal, compliance, and audit teams need to see the migration plan, not the aftermath.
• Business continuity risk: When unsupported infrastructure fails, there is no vendor on call to fix it. Organizations running approval chains, purchase requests, HR onboarding, or incident management on Nintex for SharePoint will discover that internal IT is now responsible for every production outage, without backup from either Microsoft or Nintex.

Your migration options

There are three realistic migration paths. Each has a legitimate use case. None of them offer a direct lift-and-shift from either Nintex for Office 365 or Nintex for SharePoint, so a rebuild is part of every path.

Option 1: Nintex Automation K2

K2 is Nintex’s enterprise-grade self-hosted platform and the path Nintex officially recommends for on-premises customers coming off Nintex for SharePoint. For O365 customers willing to self-host, K2 is also a Nintex-sanctioned option.

K2 works. The reasons customers pause on it come down to cost and complexity. 

One long-tenured Nintex customer, a 17-year Nintex account in Canadian healthcare, evaluated K2 when Nintex ended grandfathering on their legacy licensing and found the K2 model was roughly ten times their prior spend. Nintex was not open to negotiation. Community discussions on the Nintex forum show similar cost conversations from other enterprises.

Architecturally, K2 is meaningfully different from either Nintex legacy product. Existing workflows cannot be migrated directly. Everything rebuilds, and the rebuild requires trained K2 developers or paid professional services.

Good fit for: large enterprises with complex regulated workflows, dedicated internal automation teams, and budget for both the platform and the rebuild.

Option 2: Microsoft Power Automate

Power Automate is Microsoft’s native automation platform. It is included in many Microsoft 365 plans, integrates cleanly across the Microsoft ecosystem, and handles simple workflows reliably.

The limits are real. Licensing gets complicated once premium connectors and per-user flow licenses enter the picture. Complex approval chains routine in Nintex often require significant rework in Power Automate, frequently layered with Power Apps on top. For on-premises or air-gapped requirements, Power Automate is not the answer. The on-premises data gateway exists for hybrid scenarios but does not meet the requirements of organizations whose data cannot route back to a Microsoft cloud at all.

A Canadian healthcare customer who evaluated Power Apps during their decision captured the common finding: it would be a significant capital outlay, but the licensing blended with what they already had in Microsoft. The harder problem was the time and skillset development required, which they described as difficult, challenging, and costly.

Good fit for: organizations with primarily simple workflows, teams already skilled in the Power Platform, and cloud-first strategies that align with Microsoft’s direction without data residency constraints.

Option 3: NITRO Studio by Crow Canyon Software

A third category of tools, purpose-built SharePoint automation platforms, sits between K2’s complexity and Power Automate’s limits. NITRO Studio is in this category, and it is where most customers migrating off legacy Nintex products in regulated industries are moving.

What NITRO Studio is, in one sentence: a no-code application builder platform that runs natively inside Microsoft 365, SharePoint, and Microsoft Teams, across five deployment environments including air-gapped.

The distinction to understand is that NITRO Studio is not a forms-and-workflow tool. It is a platform for building complete line-of-business applications. It includes:

• Drag-and-drop form designer and visual workflow builder
• UI components, portals, dashboards, tiles, navigation
• List views, modern reports with charts and analytics
• Cross-site collection search and list roll-ups
• Chatbots, SMS texting, e-signature, document generation
• NITRO Copilot, AI features operating inside your Microsoft tenant

On top of the platform, Crow Canyon ships ready-to-deploy business applications: NITRO Help Desk for IT, NITRO Help Desk for HR, NITRO Purchasing, NITRO Asset Management, NITRO Request Manager, and NITRO Service Desk. These are working applications, not templates that require install and configuration.

NITRO Studio supports all five deployment environments:

• SharePoint Online in your Microsoft 365 tenant
• SharePoint Server on-premises, including 2016, 2019, and Subscription Edition
• GCC for US government organizations on Microsoft’s Government Community Cloud
• GCC High for organizations handling controlled unclassified information and ITAR-regulated data
• Air-gapped on-premises deployments via NITRO Secure, for defense, intelligence, space agencies, and nuclear operations

Good fit for: SharePoint-heavy organizations, regulated industries needing data residency controls, teams that want flat-rate predictable pricing, and organizations whose migration needs to move faster than a traditional full-rebuild cycle.

Side-by-side comparison of the three migration paths

A factor-by-factor comparison of the three replacement options most organizations are evaluating.

Why many organizations are choosing NITRO Studio

Crow Canyon Software has been building Microsoft-native business applications for more than 27 years. The company serves over 1,000 organizations across government, healthcare, banking, manufacturing, and defense, including some of the most compliance-sensitive environments in the country.

Five practical reasons Nintex customers are landing on NITRO Studio as their replacement platform:

Flat-rate pricing, unlimited workflows, and forms

NITRO Studio uses flat annual subscription pricing. One fee covers unlimited forms, unlimited workflows, and access to the full platform’s core components. Organizations switching from Nintex typically report meaningful reductions in annual automation spend. The exact amount varies with how much a team has built on Nintex, but the pattern holds: moving from a per-workflow model to a flat-rate model produces lower total cost for teams with more than a handful of active processes.

Beyond the headline number, the predictability matters. Your budget does not change as your automation footprint grows. Adding forty workflows next quarter does not change the subscription. For finance teams building multi-year operating plans, that predictability is often the deciding factor.

True on-premises and air-gapped support

Unlike most modern workflow platforms that require cloud connectivity, NITRO Studio supports genuinely offline environments. NITRO Secure runs in fully disconnected, air-gapped (GCC High) deployments. For defense, intelligence, nuclear operations, space agencies, and any organization where data residency is a hard compliance requirement, this is the differentiator. It is the reason NITRO Studio is used inside the Office of Naval Intelligence.

Data stays in your Microsoft tenant

NITRO Studio runs inside your own Microsoft 365 environment or your own on-premises SharePoint Server. Your data never leaves your infrastructure. Crow Canyon does not host workflow data on its own cloud. For organizations subject to HIPAA, CMMC, FedRAMP, or ITAR, this architecture answers the compliance question before the technical evaluation even starts.

Native Microsoft 365 and Teams integration

NITRO Studio lives inside SharePoint and Teams rather than alongside them. Employees submit requests and manage approvals inside tools they already use every day. Teams messages can be converted to Help Desk tickets directly, reducing the friction that usually leads users to bypass formal systems in favor of email.

Application Builder Platform, not a single-purpose tool

The deeper advantage is categorical. Most Nintex alternatives on the market are built around the same two components Nintex offers: forms and workflows. NITRO Studio is a no-code application builder platform. Your team builds complete departmental applications, portals, dashboards, cross-site search, and navigation, all inside one environment, rather than stitching multiple tools together. That matters practically when a team is trying to stand up something bigger than a single approval flow.

Customers that trust NITRO Studio include the State of California Franchise Tax Board, the US Department of Justice, the Office of Naval Intelligence, Ballad Health, Sony, FSU Credit Union, the US Equal Employment Opportunities Commission, California Air Resources Board, AstenJohnson, Salvation Army, and Ventura Foods. The platform is also used by space agencies, large banks, and nuclear power companies, where data residency and platform security are non-negotiable.

“NITRO Studio conquered many of SharePoint’s out-of-the-box limitations and made it easier to do many of the tasks that previously were labor-intensive and required coding, and was much more affordable than other solutions we were looking at, such as Nintex.”

Rodrigo Vargas, Senior Manager Supply Chain Quality, Ventura Foods

Migration checklist: 10 steps before your deadline

The steps below apply whether you are on Nintex for Office 365 or Nintex for SharePoint. The specific deadline changes (April 2 already passed, July 14 is ahead), but the action items are consistent.

1. Audit every active Nintex workflow and form. Document each one: business owner, trigger, frequency, criticality, and any downstream systems it touches. For O365 customers, include workflows that were active as of April 2. This is the foundational data for any migration decision.
2. Confirm which Nintex products are in scope. Verify whether you are running Nintex for Office 365, Nintex for SharePoint, or both. Check the admin panel or contact your Nintex account manager. Some organizations run both products across different business units.
3. Rank processes by business impact. Some workflows are nice to have. Others are blocking approvals, breaking invoices, or interrupting compliance trails. The first 20 percent of your migration effort will cover roughly 80 percent of the business impact if you prioritize correctly.
4. Document your data residency requirements. If your organization cannot move workflow data to a vendor cloud, write it down. It eliminates cloud-only options from your evaluation immediately. For GCC, GCC High, or air-gapped requirements, the short list narrows further.
5. Map your SharePoint Server roadmap in parallel. If you are on SharePoint Server 2016 or 2019, you also need a plan for the platform itself. SharePoint Subscription Edition or a move to SharePoint Online are the two realistic paths. Your workflow replacement must support your target environment.
6. Evaluate migration platforms. Use the comparison table in this guide to shortlist two or three options that match your deployment model, budget, and technical capacity. For most regulated organizations, this will narrow to Nintex Automation K2 and NITRO Studio, sometimes with Power Automate as a secondary option for specific use cases.
7. Request demos and scoping calls. Most platforms, including Crow Canyon Software, offer a free session to review your existing Nintex inventory and estimate a realistic migration timeline. Use the output as a scoped plan before you commit to any platform.
8. Assign a migration project owner. Without a named internal owner, migrations stall. Assign responsibility to an IT lead or department head with executive sponsorship and a weekly cadence.
9. Rebuild and test in parallel. Run the new platform alongside Nintex (where Nintex is still running). Do not decommission until all critical workflows are confirmed working on the replacement. For O365 customers, start with the highest-impact workflows first since you are already operating without the old platform.
10. Confirm go-live and decommission. Once workflows are verified on the new platform, formally decommission Nintex licenses and document the migration completion for your audit records. Include a statement on the date of cutover and any residual reliance on unsupported infrastructure.
