Legacy Google Ads scripts migration deadline set: auto-migration from September, sunset October 31, 2022

Google set the timeline for retiring the legacy scripts experience: automatic migration of remaining scripts began in September 2022 and all scripts moved to the new experience in October, with an October 31, 2022 migration deadline. Office hours were offered to help with migration.

The Google Ads scripts forum thread titled 'Migrate to the new Google Ads scripts experience by October 31, 2022' states that non-migrated scripts would be auto-migrated and might be paused.
