AWS has rebranded the original Bedrock Agents as "Bedrock Agents Classic" and set a hard cutoff: new customers cannot access it after July 30, 2026. The implication for existing users is that a migration path is open now and won't be indefinitely — AWS has a pattern of following new-customer gates with broader deprecation announcements. If your team has workflows or evaluations built on the November 2023 Agents interface, start the migration. The newer Bedrock Agents experience is already the default for new accounts.
