Update support policies without leaving old AI answers behind

Use an effective date, a replacement record and regression questions to manage a policy change across support channels.

Separate approval from availability

A document can be approved before it becomes effective. Record both dates and decide which customers the change applies to. Label the active version clearly, archive the previous one for audit, and remove superseded text from active retrieval sources when appropriate. Do not erase historical context that staff need to handle older orders or contracts.

Verify the change at the answer level

Updating a file does not prove a connected system has refreshed its index. Follow the system's refresh process, then ask the same regression questions through each supported channel. Include a question about a transaction before the effective date. Record the version the answer used and whether the old passage still appears. Keep a rollback reference if the revised material is wrong.

Fictional worked example

In a fictional change, a delivery cutoff moves from 2 PM to noon on October 15. The web FAQ, Arabic article and English article all need the same effective date. A test for an October 14 order may legitimately require the old rule; a new order should use the revised cutoff. Mark ambiguity for a person rather than assuming the latest document always governs.

Action checklist

  1. Record version, owner, approval date, effective date and replacement link.
  2. List every active copy of the changed policy.
  3. Retest before-date and after-date examples after refresh.
  4. Keep the prior version and a clear rollback procedure.
