Today, we’re sharing more details about the end of support for Azure Local, with OS version 25398.xxxx (23H2) on October 31, 2025. After this date, monthly security and quality updates stop, and Microsoft Support remains available only for upgrade assistance. Your billing continues, and your systems keep working, including registration and repair. 

There are several options to upgrade to Azure Local, with OS version 26100.xxxx (24H2) depending on which scenario applies to you.

Scenario #1: You are on Azure Local solution, with OS version 25398.xxxx 

If you’re already running the Azure Local solution, with OS version 25398.xxxx, there is no action required. You will automatically receive the upgrade to OS version 26100.xxxx via a solution update to 2509. 

If you are interested in upgrading to OS version 26100.xxxx before the 2509 release, there will be an opt-in process available in the future with production support. 

Scenario #2: You are on Azure Stack HCI and haven’t performed the solution upgrade yet 

Scenario #2a: You are still on Azure Stack HCI, version 22H2 

With the 2505 release, a direct upgrade path from version 22H2 OS (20349.xxxx) to 24H2 OS (26100.xxxx) has been made available. To ensure a validated, consistent experience, we have reduced the process to using the downloadable media and PowerShell to install the upgrade.  

If you’re running Azure Stack HCI, version 22H2 OS, we recommend taking this direct upgrade path to the version 24H2 OS. Skipping the upgrade to the version 23H2 OS will be one less upgrade hop and will help reduce reboots and maintenance planning prior to the solution upgrade. After then, perform post-OS upgrade tasks and validate the solution upgrade readiness.  

The solution upgrade for systems on the 24H2 OS is not yet supported but will be available soon. 

Scenario #2b: You are on Azure Stack HCI, version 23H2 OS  

If you performed the upgrade from Azure Stack HCI, version 22H2 OS to version 23H2 OS (25398.xxxx), but haven’t applied the solution upgrade, then we recommend that you perform post-OS upgrade tasks, validate the solution upgrade readiness, and apply the solution upgrade.

Conclusion 

We invite you to identify which scenarios apply to you and take action to upgrade your systems. On behalf of the Azure Local team, we thank you for your continuous trust and feedback!
