The article explains that Nintex’s SharePoint 2013-based workflows will reach end of support by December 2025 and stop functioning in Microsoft 365 when the SharePoint 2013 workflow engine is retired on April 2, 2026, creating security and compliance risks for organizations still running them.
Deadlines have a way of creeping up. One quarter is a distant date on a roadmap, the next it is three months away and your workflows are still running on a platform with no vendor support.
Microsoft has been retiring legacy workflow infrastructure in stages for years. SharePoint 2010 Workflows went end of life in 2020. Now, SharePoint 2013 Workflows are next. On April 2, 2026, Microsoft will permanently retire the SharePoint 2013 workflow engine in Microsoft 365, with no extensions and no grace period. Nintex Workflow for Office 365 lost support on December 31, 2025, and will stop functioning entirely when that engine is switched off.
What was once a productivity tool becomes a liability: a source of security exposure, compliance risk, and operational uncertainty. The clock is running. The question is what you do with the time you have left.
Here is a quick summary of what the timeline means in practice:
Approaching this deadline as more than a compliance task helps you get real value from the change. You already need to invest time and effort, so it makes sense to improve how your workflows run, not just replace what you had.
Moving to a modern, cloud-ready platform helps you reduce technical debt, improve reliability, and build workflows that scale with your needs. The deadline may force the move, but how you use it can shape your long-term efficiency.
Without ongoing maintenance, vulnerabilities go unaddressed, system failures become harder to resolve, and any workflow disruption has no vendor support to fall back on.
Compliance exposure also grows over time, as unsupported software is increasingly difficult to justify under audit or regulatory scrutiny. Workflows that have not been migrated off the platform by April 2026 face the real risk of breaking entirely, with no path to a fix.
Staying on an unsupported platform is not a neutral choice. The risks accumulate quietly at first, then compound quickly as the deadline passes and there is no longer a safety net in place.
Once end of life is reached, Nintex will no longer issue security patches or updates. Any vulnerabilities that emerge after April 2026 remain open, leaving workflows and the data they handle exposed.
No vendor assistance is available for unsupported software. When something breaks, the burden of diagnosis and resolution falls entirely on internal teams, with no official tooling or guidance to draw on.
Regulators and auditors increasingly scrutinize unsupported software in workflow environments. Running business-critical processes on an end-of-life platform is difficult to justify under most compliance frameworks.
Without ongoing maintenance, the risk of system failures grows over time. Disruptions that would previously have been patched quickly can cascade into prolonged downtime and manual workarounds.
Organizations that wait until the final months face compressed timelines and higher implementation pressure. Starting early means more time to evaluate alternatives, plan the migration properly, and avoid a rushed, like-for-like replacement.
A successful migration does not start with picking a new platform. It starts with understanding what you have, what needs to move, and what needs to change. Here is how to approach it.
Take stock of every workflow currently running on Nintex or SharePoint 2013. Note which ones are business-critical, which are rarely used, and which may no longer be needed at all. A clear picture of what you have makes every decision after this one easier.
Some workflows are straightforward to move. Others have custom logic, integrations, or dependencies that need more thought. Knowing where the complexity sits helps you sequence the migration sensibly and avoid surprises mid-project.
Before you evaluate options, get clear on what your workflows need to do. Talk to the people who use them daily. You may find requirements that were never met by the legacy setup, or workarounds that have quietly become part of the process.
Moving to a modern platform is not just a technical decision; it is a business one. Tools like FlowForma are purpose-built for exactly this moment: no-code, natively integrated with Microsoft 365, and designed to make your workflows faster to build, easier to manage, and simpler to scale as your needs evolve.
New tooling only delivers value if your team actually uses it. Communicate the change early, involve key users in testing, and ensure training is part of your project plan from the start.
April 2026 is the hard stop. Build your timeline from that date backwards, accounting for discovery, build, testing, and rollout. Leave room for the unexpected; complex migrations rarely go exactly to plan.
When Nintex users face end of life, the path Nintex points to is Nintex Automation Cloud K2: their own next-generation platform. And while staying within the Nintex ecosystem might seem like the easiest route, it is worth pausing before you follow that path automatically.
Nintex’s K2 platform
Staying within the Nintex ecosystem and upgrading to K2 is one option, but it comes with a significantly higher cost and a more complex platform that takes time to learn and deploy. For many organizations, it solves the deadline problem without addressing the underlying one.
FlowForma is purpose-built for Microsoft 365, no-code by design, and AI-powered from the ground up. Your team can migrate existing processes and modernize them at the same time, without the overhead or complexity of a heavy enterprise platform.
Both platforms can handle complex workflows, but the experience of building, managing, and scaling on each one is quite different. Here is how they compare across the areas that matter most to your team.

Here’s what FlowForma brings to the table:
Your business teams can build, test, and iterate on workflows without waiting for developer time or writing a single line of code. FlowForma's drag-and-drop form and workflow builder puts process ownership where it belongs: with the people who actually run the processes.
FlowForma's AI Copilot lets you create a fully functional workflow in minutes by uploading a process document, diagram, or even a text description. Just elaborate your process with conditions, logic, rules, triggers, and other modifications, and FlowForma AI Copilot will take it from there.
Here’s a demo explaining how to automate onboarding in using FlowForma AI Copilot.
The Discovery Agent turns conversations and meeting notes into ready-to-run processes.
