- migrateTraffic: boolean, Set to true to gradually shift traffic from one version to another single version. By default, traffic is shifted immediately. For gradual traffic migration, the target version must be located within instances that are configured for both warmup requests (https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#inboundservicetype) and automatic scaling (https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services.versions#automaticscaling). You must specify the shardBy (https://cloud.google.com/appengine/docs/admin-api/reference/rest/v1/apps.services#shardby) field in the Service resource. Gradual traffic migration is not supported in the App Engine flexible environment. For examples, see Migrating and Splitting Traffic (https://cloud.google.com/appengine/docs/admin-api/migrating-splitting-traffic).
