Sitecore XP 10.3 Support Has Ended

As of December 31, 2025, mainstream support for Sitecore XP 10.3 has officially ended. If your organization is still running on this version, or an even older release, now is the time to evaluate your options and chart a path forward.

First of all, you're not "out of support".

If you have a Sitecore Partner, like Nishtech, you're 10.3 instance will be supported until 2029.

Understanding Your Current Position

For organizations running Sitecore XP 10.3 or earlier, the end of mainstream support raises important questions about your platform's future. The main question is what do you lose? Do you still get security patches? Here's what many organizations don't realize: if you're working with a Sitecore partner, you're not facing an immediate crisis and yes, you'll still get patches.

The Partner Advantage: Extended Support Until 2029

Organizations with an active Sitecore partner relationship have access to extended support options that provide meaningful breathing room, and crucially, you'll continue receiving security updates through December 31, 2028.

That's an additional two years of security patch coverage and compliance peace of mind.

What changes under extended support? You won't have access to direct Sitecore assistance for troubleshooting, feature bug fixes, or new feature releases. This is not a problem. Why? If you have a Sitecore partner, your partner handles most of this. For many organizations, that's an acceptable trade-off, especially when your partner can provide the hands-on support you need for day-to-day operations and issue resolution.

This extended support window means you don't have to make rushed decisions or execute hurried migrations. Instead, you can take a thoughtful, strategic approach to your platform's future by evaluating your options, building internal consensus, and planning an upgrade that aligns with your broader digital strategy.

If you're not currently working with a Sitecore partner and want to explore these extended support options, now is the time to start that conversation.

Option One: Upgrade to Sitecore XP 10.4

For organizations that want to extend their on-premises or hybrid Sitecore investment while modernizing their platform, upgrading to Sitecore XP 10.4 represents a compelling middle path.

An upgrade to 10.4 extends your support window through the end of 2027 under mainstream support, with extended support options reaching all the way to 2030. That's up to five more years of runway on a proven, powerful platform.

Beyond the support timeline, version 10.4 brings meaningful improvements to the platform. You'll see enhanced performance, updated security frameworks, and refined developer experiences that make your team more productive. It's an opportunity to modernize your existing implementation while preserving the customizations and integrations you've built over the years.

For many organizations, this upgrade path offers the best of both worlds: continued investment protection with meaningful platform improvements, all without the complexity of a full platform transformation.

Nishtech has executed quite a few of these upgrades, and this is considered a fairly minor upgrade in terms of complexity, time and cost.

Option Two: Embrace the Future with SitecoreAI

Perhaps the end of 10.3 support is the catalyst you've been waiting for. If your organization is ready to think bigger, to fundamentally reimagine how you create, manage, and deliver digital experiences, this might be the moment to make the leap into Sitecore's next-generation cloud platform and AI capabilities.

Sitecore has invested heavily in building a composable, cloud-native architecture that gives organizations unprecedented flexibility. SitecoreAI and the XM Cloud platform offer a fundamentally different approach: faster deployments, automatic updates, reduced infrastructure overhead, built-in agentic AI features and the ability to innovate at the speed your business demands.

And then there's Content Hub, Personalization, CDP and Sitecore Search... all included now.

SitecoreAI capabilities are transforming how marketing teams work by providing an entire suite of robust, mature DXP features in one SaaS hosted solution.

Making this leap requires more planning and organizational commitment than a version upgrade, but the potential payoff is transformational. You'll like want to consider a re-branding or redesign of your site if you choose this path.

Making Your Decision

Every organization's situation is unique. Your decision will depend on factors like your current technical debt, your team's capabilities, your budget cycles, and your broader digital transformation roadmap.

Here's a simple framework to guide your thinking:

Choose extended partner support if you need time to plan and aren't ready to make significant platform changes in the near term. This buys you runway through 2028 while you develop your longer-term strategy. This is close to the "do nothing" option as long as you have a partner supporting you.

Choose the 10.4 upgrade if you want to modernize while preserving your existing investment and extending your support window to 2030. This is ideal for organizations that have significant customizations or aren't yet ready for a cloud migration.

Choose SitecoreAI if you're ready to transform your digital experience capabilities, reduce infrastructure complexity, and leverage the latest in AI-powered marketing technology. This is the path for organizations thinking about where they want to be in five to ten years, not just the next support cycle.

The Time to Act Is Now

Regardless of which path you choose, Nishtech can support you and guide you. Running on an unsupported platform exposes your organization to security vulnerabilities, compliance risks, and the accumulating technical debt that makes future migrations even more complex.

The end of 10.3 support isn't a crisis. It's an opportunity. An opportunity to strengthen your security posture, modernize your platform, and position your organization for the future of digital experiences.
