App Service plan Tier change

Question

Hi Team ,

I am trying to change my app service plan from isolated tier to standard tier. But not getting the option in azure portal for standard tier.

Please let me know it is possible or not

Also if above is not possible, Can we create a new app service plan in standard tier and move the app services which are currently mapped with app service plan in isolated tier to newly created app service plan

Regards,
Manisankar

Hi @Manisankar Murugan ,

Currently, you can not change your app service plan from isolated tier to standard tier. You can move an app to another App Service plan, as long as the source plan and the target plan are in the same resource group and geographical region.

Azure deploys each new App Service plan into a deployment unit, internally called a webspace. Each region can have many webspaces, but your app can only move between plans that are created in the same webspace. An App Service Environment is an isolated webspace, so apps can be moved between plans in the same App Service Environment, but not between plans in different App Service Environments.

You can’t specify the webspace you want when creating a plan, but it’s possible to ensure that a plan is created in the same webspace as an existing plan. In brief, all plans created with the same resource group and region combination are deployed into the same webspace. For example, if you created a plan in resource group A and region B, then any plan you subsequently create in resource group A and region B is deployed into the same webspace. Note that plans can’t move webspaces after they’re created, so you can’t move a plan into “the same webspace” as another plan by moving it to another resource group.

Please read this documentation for more details. Hope that helps.,

Thanks,
Grace
