ITIL v5 vs ITIL 4

The short version

ITIL v5 is a meaningful update, not a cosmetic rebrand. The three biggest changes are the expansion of the value chain from 6 to 8 activities, the addition of a full AI capability model, and the introduction of data governance as a standalone practice. Everything that was in ITIL 4 is still relevant — the guiding principles, the four dimensions, and the continual improvement model are all retained unchanged.

If you already hold an ITIL 4 Foundation certification, you can upgrade to v5 through a bridge exam. PeopleCert charges approximately $263 for this route, compared to $690 for the standalone exam.

Should you upgrade from ITIL 4?

If you passed ITIL 4 Foundation and are working in an organisation that is actively adopting AI in its IT operations — yes. The AI content in v5 is genuinely new and increasingly tested in role interviews. Hiring managers in 2026 are beginning to ask specifically about AI governance, data governance, and the 6C model in ITIL-related roles.

If you are in a stable role and your organisation has not yet moved to v5 — there is no urgent pressure. ITIL 4 certifications remain valid and widely recognised. The bridge exam at $263 is low-cost enough that it makes sense to upgrade when you have a study window.

If you have not yet sat any ITIL exam — sit the v5 exam directly. There is no reason to start with ITIL 4 when v5 is the current standard.
