Updates the specified Version resource. You can specify the following fields depending on the App Engine environment and type of scaling that the version resource uses:

**Standard environment**

- [`instanceClass`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.instance_class)

*automatic scaling* in the standard environment:

- [`automaticScaling.min_idle_instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.automatic_scaling)
- [`automaticScaling.max_idle_instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.automatic_scaling)
- [`automaticScaling.standard_scheduler_settings.max_instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#StandardSchedulerSettings)
- [`automaticScaling.standard_scheduler_settings.min_instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#StandardSchedulerSettings)
- [`automaticScaling.standard_scheduler_settings.target_cpu_utilization`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#StandardSchedulerSettings)
- [`automaticScaling.standard_scheduler_settings.target_throughput_utilization`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#StandardSchedulerSettings)

*basic scaling* or *manual scaling* in the standard environment:

- [`servingStatus`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.serving_status)
- [`manualScaling.instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#manualscaling)

**Flexible environment**

- [`servingStatus`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.serving_status)

*automatic scaling* in the flexible environment:

- [`automaticScaling.min_total_instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.automatic_scaling)
- [`automaticScaling.max_total_instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.automatic_scaling)
- [`automaticScaling.cool_down_period_sec`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.automatic_scaling)
- [`automaticScaling.cpu_utilization.target_utilization`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#Version.FIELDS.automatic_scaling)

*manual scaling* in the flexible environment:

- [`manualScaling.instances`](https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#manualscaling)
