Sitecore 9.3 End of Life: Upgrade to 10.4 — and Save on Azure While You’re At It
If your organisation is still running Sitecore 9.3, the clock is ticking. Mainstream support for Sitecore 9.3 ends on 31 December 2025, which means that after this date, your platform will no longer receive regular updates, security patches, or official support from Sitecore. That’s less than two months away — and now is the perfect time to plan your upgrade and take advantage of major opportunities in performance and cost optimisation.
What End of Life means for Sitecore 9.3 users
When Sitecore ends mainstream support, it signals the end of active maintenance and feature updates for that version. After 31 December 2025:
- No more security updates will be provided.
- Limited or no vendor support for incidents or bugs.
- Compliance and risk exposure increase, especially in regulated industries.
- Higher maintenance costs as your environment ages.
Continuing to operate an unsupported version can quickly become risky - and expensive.
Why Upgrading to Sitecore 10.4 Makes Sense
Upgrading to Sitecore 10.4 keeps your digital experience platform fully supported until at least 2032, giving you long-term stability and access to the latest features, performance improvements, and integrations.
Key benefits include:
- Extended support lifecycle - Mainstream support until 2027, extended to 2030, and sustaining support through 2032.
- Improved architecture and tools for developers and content teams.
- Enhanced security and cloud compatibility with Azure and XM Cloud.
- Smoother upgrade path to headless and composable Sitecore options in the future.
Optimise Your Azure Hosting During the Upgrade
Upgrading is the perfect time to right-size and optimise your Azure environment.
At PING, we’ve helped Sitecore customers save 20–30% on Azure hosting costs by aligning infrastructure with real-world usage — improving performance while reducing waste.
That includes:
- Reducing over-provisioned environments.
- Introducing autoscaling and cost-governance controls.
- Streamlining content delivery and caching configurations for faster response times.
These optimisations often pay for themselves within months - and they deliver ongoing savings long after the upgrade is complete.
Performance Tuning for a Faster, More Reliable Sitecore
Beyond cost savings, performance tuning can dramatically improve site speed, reliability, and publishing workflows.
By addressing caching, indexing, and environment configuration, organisations often see:
- Up to 50% faster load times.
- Improved scalability and stability during traffic peaks.
- Smoother content authoring and publishing experiences.
Combining performance tuning with your upgrade to 10.4 ensures you get a faster, more efficient platform that’s ready for future growth.
