Clarification needed: Will production bots stop working after Azure Language Studio retirement?

I noticed an in-portal notification saying Language Studio will retire on February 16, but the Microsoft documentation states the official retirement date is March 20, 2027.

Before I take action, I need to confirm: If we do not migrate our Custom Question Answering and Conversational Language Understanding (CLU) projects from Language Studio to Azure AI Foundry, will our existing production bots stop working?

According to the documentation, after March 20, 2027 the Language Studio UI will no longer be available, but existing projects, data, and service endpoints will not be impacted. Reference: https://dori-uw-1.kuma-moon.com/en-us/azure/ai-services/language-service/migration-studio-to-foundry

Can Microsoft please confirm whether the runtime endpoints for CLU and CQA will continue working post-retirement?

    Check the official announcement and timeline, update your bots to the supported SDKs and APIs as soon as possible, test the updated code in a staging environment before switching production, verify authentication and endpoint changes, monitor logs and telemetry for errors during the transition, roll out changes gradually to limit impact, and contact Microsoft support if you see breaking issues or need clarification; communicating the plan and timeline to your users and stakeholders will also help avoid surprises.
