Transition audit

A transition audit was the audit that moved an ISO 27001:2013 certificate to the 2022 edition; the transition period closed on 31 October 2025.

Also called ISO 27001:2022 transition

After ISO/IEC 27001:2022 was published, certified organizations had three years to update their ISMS, in particular the Statement of Applicability against the restructured Annex A, and to have a certification body verify the changes in a dedicated transition audit or as part of a surveillance or recertification audit. Certificates issued against the 2013 edition expired or were withdrawn at the end of the period.

An organization whose 2013 certificate lapsed cannot transition any more: it needs a full Stage 1 and Stage 2 audit against the 2022 edition.
