ExternalManagedBackendBucketMigrationState(value)
Specifies the canary migration state for the backend buckets
attached to this forwarding rule. Possible values are PREPARE,
TEST_BY_PERCENTAGE, and TEST_ALL_TRAFFIC. To begin the migration
from EXTERNAL to EXTERNAL_MANAGED, the state must be changed to
PREPARE. The state must be changed to TEST_ALL_TRAFFIC before the
loadBalancingScheme can be changed to EXTERNAL_MANAGED. Optionally,
the TEST_BY_PERCENTAGE state can be used to migrate traffic to
backend buckets attached to this forwarding rule by percentage using
externalManagedBackendBucketMigrationTestingPercentage. Rolling back
a migration requires the states to be set in reverse order. So
changing the scheme from EXTERNAL_MANAGED to EXTERNAL requires the
state to be set to TEST_ALL_TRAFFIC at the same time. Optionally,
the TEST_BY_PERCENTAGE state can be used to migrate some traffic
back to EXTERNAL or PREPARE can be used to migrate all traffic back
to EXTERNAL.
