Saw this warning on SoM's logging dashboard: "Action required by May 15, 2017. All export sinks using the v1 format must be migrated to use the v2 format."

See https://cloud.google.com/logging/docs/migration-v2?hl=en_US&_ga=1.140135921.312577391.1492033099#migrate-exports for more details.

Might be a no-op.
