Nintex Workflow End of Life: What You Need to Do Before April 2026
If your organization still relies on Nintex On-Premise or Nintex Workflow for Office 365, this is a critical moment. Microsoft and Nintex are phasing out support, meaning workflows built on SharePoint 2013 or 2010 engines will stop working or will be unsupported by mid2026.
Here’s what you need to know and how to prepare.
Key Deadlines You Can't Ignore
| Event | Date | Impact |
|---|---|---|
| Nintex Workflow for O365 end of support | Dec 31, 2025 | You stop receiving updates, patches, or assistance (Nintex Community) |
| SharePoint 2013 workflows end | Apr 2, 2026 | Microsoft turns off the engine - workflows using this platform cease (Microsoft Support) |
| Nintex workflows on 2013 engine stop functioning | Apr 2, 2026 | Even existing processes break without direct recourse (Nintex Community) |
| SharePoint 2010 workflows die | July 14, 2026 | If you're on Subscription Edition - no workaround (Microsoft Support) |
That means if you're still running Nintex on-premises tied to SharePoint 2013, support ends Dec 2025 and full functionality stops by Apr 2026.
What the End-of-Life (EOL) Really Means
- No security patches or fixes after deadlines.
- Workflows may stop unpredictably, leading to downtime, productivity loss, or compliance issues.
- Vendor support evaporates, especially where Microsoft dependencies break.
Nintex warns that workflows will stop entirely after April 2, 2026, “with no recourse or workaround.” (Nintex Community)
Why This Is Happening
Microsoft is shifting focus from legacy SharePoint workflow engines to Power Automate and cloud-native automation. From a security standpoint, unsupported tools pose risks, and from a product standpoint, Microsoft wants everyone on modern platforms. Nintex technologies that rely on these frameworks, including Nintex On-Prem and Workflow for Office 365, are therefore being sunset in line with Microsoft’s support lifecycle.
What Your Options Are
- Migrate to Nintex Automation Cloud: Works with no-code/low-code logic and modern UI.Be ready: migration isn’t plug and play. Scripts and workflows require rebuilding and extensive testing, especially if they’re complex (FlowForma).
- Licensing costs are higher than on-prem, sometimes 4–5× current spend (skybow.com).
- Build an inventory of workflows: where are they used, what do they do, who owns them. Pro tip: t-shirt size your workflows based on the number of actions to estimate complexity.
- Move to Microsoft Power Automate + Power Apps: Fully modern, integrated with Microsoft 365, Azure, and Dataverse.
- Supports governance, security, and scalability at the enterprise level.
- Many organizations on Reddit report higher satisfaction and better alignment with Microsoft’s roadmap (Reddit).
- Stay on-prem at your own risk: Not recommended. After support ends, you're exposed to security vulnerabilities, compliance issues, and technical failures with no official remedy.
Steps to Take Now
-
- Build an inventory of workflows: where are they used, what do they do, who owns them.
- Assess priority and complexity: which automations are business critical vs. nice to have.
- Choose your modernization path: Nintex Cloud, Power Platform, or alternative.
- Pilot on your most important workflows: test performance, user experience, and integration.
- Roll out with governance: establish Center of Excellence practices with version control, auditing, reusable components, and security.
- Decommission the old: turn off/create new SharePoint 2013 workflows via PowerShell or admin portal before April 2026 (Microsoft Support).
Why You Can't Delay
Waiting comes with real consequences. Unsupported systems increase cybersecurity risk, and relying on retired technology stacks can lead to costly, unexpected downtime. Meanwhile, the return on modern platforms is clear: Forrester found that organizations using Power Automate saw a 248% ROI and a net present value of $39.8 million over three years (Microsoft Support).
