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.

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

Nintex for Office 365 Stopped Working on April 2. Here’s What to Do Now.

  If you woke up on April 2 and your Nintex for Office 365 workflows and forms were not running, you are not alone. Microsoft retired the SharePoint 2013 workflow engine on April 2, 2026. On the same day, it retired the SharePoint Add-In app model. Both of these were the infrastructure Nintex for Office 365 was built on. When that infrastructure went away, so did Nintex for Office 365. Nintex flagged this as end of life back in December 2023. Support ended on December 31, 2025. Execution ended on April 2, 2026. There is no patch. There is no recourse. Any approval flow, notification, form, or routing rule that depended on Nintex for Office 365 stopped working that day. This blog covers what happened, why it caught so many teams off guard, and the three migration paths that actually work. READ MORE

Nintex for SharePoint Is Running Out of Runway: What On-Premises Admins Must Do Before July 14, 2026

  If you manage SharePoint on-premises and your organization runs Nintex workflows, you have a deadline on your calendar. July 14, 2026. That is when Microsoft ends extended support for SharePoint Server 2016 and 2019. It is also when the SharePoint 2010 workflow engine goes unsupported, InfoPath Forms retires, and SharePoint Designer 2013 retires. Nintex for SharePoint, the on-premises workflow product many organizations rely on, runs on that infrastructure. When the infrastructure loses support, Nintex for SharePoint loses its foundation. Nintex itself ties its on-premises product’s timeline to Microsoft’s SharePoint Server support window. On its own end-of-support page, Nintex tells customers that with SharePoint Server 2016 and 2019 ending in July 2026, organizations should start planning immediately. This blog covers what is ending, why on-prem organizations face a harder problem than their cloud peers, and the three migration paths that work for regulated environments. READ M...

Nintex vs NITRO Studio: Which Is the Better Alternative in 2026?

Image
  Your Nintex renewal is coming. Or the quote already landed, and the number made you pause. Either way, you are here because you are weighing whether Nintex is still the right fit for your environment, or whether a different platform makes more sense for what your team actually needs to build. This comparison is written for that decision. The important thing to understand up front is that Nintex and NITRO Studio are not in the same category of product. Nintex is a forms and workflow automation tool. NITRO Studio is a no-code application builder platform. That distinction shapes every downstream comparison: pricing, deployment, support, and what your team can actually get done with each one. This piece walks through that category difference, then compares the two side by side on pricing, deployment flexibility, ease of use, support, and fit for regulated industries. No filler, no hype, just the detail you need to make the call. READ MORE
