VMware Cloud Foundation 4.3 EOL: Oct 31, 2023 Deadline

VMware Cloud Foundation 4.3 EOL: The Six-Month Deadline

VMware Cloud Foundation 4.3 is scheduled to reach end of life (EOL) and end of active support on October 31, 2023. Because 4.3 is not a Long-Term Support (LTS) release, infrastructure teams have a firm deadline to either upgrade or secure alternative maintenance. The latest version in this specific line is 4.3.1, which shares the same expiration date.

With roughly six months remaining, the window for a comfortable migration is closing.

A Realistic Migration Timeline

Working backward from the October 31, 2023 deadline reveals how little time remains for a major infrastructure upgrade. Once you factor in procurement cycles, change freezes, and testing, a six-month window is highly compressed:

October 2023: Final cutover, rollback contingencies, and validation.
August - September 2023: Implementation and extensive testing in staging environments.
June - July 2023: Securing budget approvals, finalizing vendor contracts, and navigating summer change freezes.
May 2023: Architecture planning, compatibility checks, and resource allocation.

Any delays in procurement or unexpected issues during staging can push the final cutover past the official lifecycle expiration.

The Risks of Missing the Deadline

Running VMware Cloud Foundation 4.3 past its end of active support date exposes your infrastructure to significant risks. Without vendor support, your organization will no longer receive security patches, bug fixes, or performance updates. This not only creates operational vulnerabilities but can also lead to compliance violations for businesses required to maintain supported software stacks.

Removing the Deadline Pressure

You do not have to force a rushed migration. Engaging a VMware third-party support provider allows you to decouple your infrastructure strategy from the vendor's release schedule.

By locking in third-party maintenance now, your team ensures that VMware Cloud Foundation 4.3 remains fully supported, secure, and operational well past the October 31 cutoff. This approach provides the flexibility to plan a migration on your own timeline or simply continue running a stable environment indefinitely.

Still running VMware Cloud Foundation 4.3 after end of life?

VMware Cloud Foundation 4.3 leaves vendor support on October 31, 2023; after that, fixes and security updates stop or move to a paid extended programme. Third-party support keeps it in production on your timetable: issue resolution and workarounds from engineers who know the release, vulnerability assessment and mitigation guidance for new CVEs, and the documentation auditors ask for, typically at 40-70% below the vendor's extended support price.

How we can help

Keep it supported after end of life

The vendor's date doesn't have to be yours. Our engineers keep VMware Cloud Foundation 4.3 running after official support ends — independent third-party support that covers most operational issues, typically at 40-70% below the last renewal quote.

Migration services

When you do decide to move, we plan and execute the migration. Your current environment stays under vendor support while your contract is active — and if the renewal lapses mid-move, our third-party support covers most issues until the last workload is off it.
