Azure Functions: runtime v3 on Linux Consumption retirement
After 30 Sep 2026, function apps using Azure Functions runtime v3 on the Linux Consumption plan no longer start or process executions.
Retired , 30 Sep 2026
What breaks
Azure Functions runtime v3 was retired on December 13, 2022, and Azure enforces that retirement for Linux Consumption function apps still on runtime v3. After 30 Sep 2026, function apps using runtime v3 on Linux Consumption no longer start or process executions. Existing deployments in this configuration stop functioning.
Who is affected
Affected versions
3.x
What to do
- Migrate affected apps to Azure Functions runtime v4 before the enforcement date. See Migrate apps from Azure Functions version 3.x to version 4.x.
- The Linux Consumption plan has its own retirement date in September 2028, so Microsoft encourages migrating to Azure Functions Flex Consumption, which supports runtime v4. See Migrate Azure Functions Linux Consumption plan apps to the Flex Consumption plan.
Replacement
Azure Functions runtime v4
