Terraform Configuration Files

resource "azurerm_virtual_desktop_host_pool" "hostpool" {

}

Debug Output/Panic Output

# module.avd["hp-avd-oneim-prod"].azurerm_virtual_desktop_host_pool.hostpool must be replaced
-/+ resource "azurerm_virtual_desktop_host_pool" "hostpool" {
        name                             = "hp-avd-prod"
      ~ preferred_app_group_type         = "Desktop" -> "RailApplications" # forces replacement
        # (12 unchanged attributes hidden)
        # (1 unchanged block hidden)
    }

Expected Behaviour

While change the preferred_app_group_type from "Desktop" to "RailApplications" should not trigger a replacement of the complete host pool resource.

Actual Behaviour

Change of the attribute replace the host pool and alle related resources (application groups, hosts etc.). Hosts have to add manually after replacing of host pool!

Thanks for taking the time to raise this issue, as noted in the terraform documentation:

preferred_app_group_type - (Optional) Option to specify the preferred Application Group type for the Virtual Desktop Host Pool. Valid options are None, Desktop or RailApplications. Default is Desktop. Changing this forces a new resource to be created.

Changing the preferred_app_group_type forces a new resource to be created, this is expected behavior.

@rcskosir thanks for the fast response! :D

We are aware of the documentation, but we think that's unnecessary! Because it's possible to change this value through the azure portal without the need of replacement.
