September 2026 marked a quiet but important milestone for Enterprise Vault customers. With Enterprise Vault 14.5 moving out of standard support on 4 September, no Enterprise Vault 14.x release now has standard support. One release has already reached End of Support Life, and the next follows in March 2027.

Many of the Enterprise Vault estates we work with across the GCC still run a 14.x release. If yours is one of them, this is the point to turn "we should upgrade at some point" into a dated plan.

What happened

According to the vendor's published Enterprise Vault release lifecycle dates:

Release	End of standard support	End of Support Life
Enterprise Vault 14.3	5 September 2025	5 September 2026 (passed)
Enterprise Vault 14.4	6 March 2026	1 March 2027
Enterprise Vault 14.5	4 September 2026	4 September 2027

Enterprise Vault 14.2 and earlier releases are already past End of Support Life.

Between the end of standard support and End of Support Life, the vendor states that Extended Technical Support must be purchased to receive support. After End of Support Life, the release is no longer supported at all.

At the same time, the upgrade target has moved. Enterprise Vault 16, the current release, became generally available in May 2026, and the vendor's What's new page lists skip-version upgrade support from Enterprise Vault 14.x directly to version 16. The vendor has not yet published support dates for version 16.

What this means for GCC customers

It is a compliance question, not only an IT one. GCC banks, insurers and government entities keep email and file archives because regulators, auditors and legal teams expect records to be retained, searchable and producible. An archive platform that no longer receives security fixes is harder to defend in an audit or a vendor risk review, and the conversation moves from "is the archive working?" to "why is a critical records system unsupported?"

Extended Technical Support buys time, not a plan. It is a paid bridge for releases past standard support. It does not change the End of Support Life date, so treat it as cover while you upgrade rather than as a way to postpone the decision.

Upgrades take longer than the calendar suggests. A large archive is not a single installer. Index health, SQL and Windows versions, Exchange or Microsoft 365 integration, storage, Discovery Accelerator and Compliance Accelerator, backups and third-party integrations all have to line up. In the GCC, year-end change freezes and Ramadan schedules can easily remove weeks from the window. For 14.4 sites, 1 March 2027 is closer than it looks.

The direct path simplifies one step, not the whole project. Skip-version support from 14.x to 16 avoids an intermediate 15.x upgrade, but each estate still needs its own compatibility, recovery and validation plan. Our Enterprise Vault 16 Upgrade Guide covers those prerequisites in detail.

On-premises control remains an option. For organisations with data residency and sovereignty obligations, Enterprise Vault 16 keeps the customer-managed, in-country deployment model many GCC regulated organisations depend on. Upgrading does not have to mean moving archives out of the country.

Practical recommendations

Confirm your exact release. Check the build on every Enterprise Vault server, including Discovery Accelerator, Compliance Accelerator and any standby or disaster recovery servers.
Map your dates. Record the End of Support Life date for each release you run, and whether Extended Technical Support is in place.
Check your entitlement. Make sure your maintenance or subscription covers an upgrade to version 16 before you plan around it.
Assess the environment first. Review index health, storage, SQL, Windows, Exchange and Microsoft 365 integration, and any third-party tools against the version 16 compatibility documentation.
Fix known issues before you upgrade. Failed indexes, MSMQ backlogs and storage problems are cheaper to solve before the change than during it.
Plan recovery and validation. Agree how you would roll back, and how you will prove that archiving, search, retrieval, legal holds and exports work afterwards.
Schedule around freezes. Work back from your End of Support Life date and your organisation's change freezes so the upgrade has room for testing.

FAQ

Is Enterprise Vault 14.x still supported?

Not under standard support. Enterprise Vault 14.3 reached End of Support Life on 5 September 2026. Enterprise Vault 14.4 and 14.5 can only be supported through purchased Extended Technical Support until 1 March 2027 and 4 September 2027 respectively.

Can I upgrade from Enterprise Vault 14.x directly to version 16?

The vendor lists skip-version upgrade support from 14.x directly to Enterprise Vault 16. A site on a later 14.x update may first need to be at the matching base release, so check the supported upgrade paths, release notes and compatibility charts for your exact build before planning the change.

What happens if we keep running 14.x after End of Support Life?

The archive will keep running, but the release receives no further support or fixes from the vendor. For regulated organisations, that usually becomes an audit and risk finding, so plan the upgrade before the date rather than after.
