+# Upgrading to Project Factory v2.0 (from v1.X)
+
+The v2.0 release of Project Factory is a backwards incompatible release. It only affects users who utilize the `app_engine` argument.
+
+## Migration Instructions
+
+### App Engine Argument Changes
+
+Version 1.X of Project Factory used the `app_engine` map variable to configure App Engine:
+
+```hcl
+/// @file main.tf
+module "project-factory" {
+  # ...
+  app_engine {
+    location_id = "${var.region}"
+    auth_domain = "${var.domain}"
+
+    feature_settings = [
+      {
+        split_health_checks = false
+      },
+    ]
+  }
+}
+```
+
+Version 2.X of Project Factory uses a new module named `app_engine`:
+
+```hcl
+/// @file main.tf
+module "project-factory" {
+  # ...
+}
+
+module "app-engine" {
+  source  = "terraform-google-modules/project-factory/google//modules/app_engine"
+  version = "~> 2.0"
+
+  project     = "${var.project_id}
+  location_id = "${var.region}"
+  auth_domain = "${var.domain}"
+
+  feature_settings = [
+    {
+      split_health_checks = true
+    },
+  ]
+}
+```
+
+### App Engine State Import
+
+The new implementation uses the `google_app_engine_application` resource which needs to be imported into the current state (make sure to replace `$YOUR_PROJECT_ID`):
+
+```sh
+terraform import module.app-engine.google_app_engine_application.main $YOUR_PROJECT_ID
+```
+
+After importing, run `terraform` `plan` and `apply`.
