App Service Environment version 1 and version 2 will be retired on 31 August 2024
Published date: 21 April, 2023
In August 2021, we announced Azure Cloud Services (classic) will be retiring on 31 August 2024. As App Service Environment v1 and v2 run on Azure Cloud Services (classic), we will retire App Service Environment v1 and v2 on the same date. Before that date, you must migrate to App Service Environment v3.
After 31 August 2024, App Service Environment v1 and v2 will no longer be supported and these App Service Environments and the applications running on them will be deleted and any application data associated with them will be lost.
App Service Environment is an App Service feature that provides a fully isolated and dedicated environment for securely running App Service apps at high scale. App Service Environment v3 is easier to use, runs on more powerful infrastructure that can go up to 64 cores and 256 GB RAM with faster scaling speeds for both Windows and Linux, and has much simpler network topology. Here’s a quick comparison between App Service Environment v1/v2 to v3.

To avoid service disruption, please follow the steps to migrate to App Service Environment v3 by 31 August 2024.
