VCF 9.1 - VCF Instance & Fleet Consolidation/Relocation

by // 2 Comments

An interesting set of deployment scenarios has been coming up as customers begin planning their upgrade to VMware Cloud Foundation (VCF) 9.1. Customers' existing deployments are often the result of years of organic growth, evolving operational requirements, and infrastructure constraints. Whether driven by available hardware, project timelines, or changing business priorities, today's deployment topology is not always the one customers would choose if they were starting from scratch.

For some customers, rather than performing a like-for-like upgrade, customers is using the transition to VCF 9.1 as a natural opportunity to consolidate and/or relocate some of their existing deployments, better aligning their architecture with current operational and infrastructure requirements.

UPDATE (08/01/2026) - This blog post has been updated with additional information, including step-by-step instructions for relocating VCF 5.x and 9.0.x Instances between Aria Operations/VCF Operations instances, example screenshots that walk through a relocation workflow, and a summary table covering all supported relocation scenarios. As part of validating these workflows, I have also shared this feedback with the product team to help improve the official VCF product documentation with this guidance.

VCF 9.1 - Understanding VCF Express Patches

by // Leave a Comment

AI has fundamentally changed the software industry through its ability to discover software vulnerabilities at an unprecedented pace. This has driven software vendors to adopt faster release cadences, making more frequent software updates the new industry norm.

VMware Cloud Foundation (VCF) is no exception. With the unified versioning introduced in VCF 9, several release types are available to deliver updates, each serving a specific purpose.

The following diagram summarizes the VCF unified versioning model, showing whether each release type is synchronized across the VCF software stack or delivered independently, along with its installation method.


Rather than bundling security fixes into the next scheduled maintenance release, Express Patches allow them to be delivered as soon as they are available. Unlike upgrades, which must be applied in a specific order, Express Patches can be applied in any order, reducing some of the overhead in rolling out the fixes.

As a result of this faster release cadence, product fixes can also be delivered much sooner, rather than waiting for the next maintenance or minor release.

What Host Lifecycle Operations Are Available after Importing vCenter into VCF 9.x Fleet?

by // 3 Comments

VMware Cloud Foundation (VCF) first introduced the Brownfield Import capability in VCF 5.2, making it easy for customers to onboard their existing vSphere environments into a VCF deployment. While the Brownfield Import capability had some limitations in earlier releases, it has seen significant enhancements since VCF 9.0 and now provides a native onboarding experience using either the VCF Installer or as a Day-N operation within VCF Operations.

While some customers may have the opportunity to deploy a brand new VCF 9.1 Fleet as part of a hardware refresh initiative, the vast majority will start by converting an existing vSphere environment into their initial VCF Management Domain and then import their remaining vSphere environments as VCF Workload Domains.

In addition to providing centralized visibility and lifecycle management (patching and upgrades) for imported environments, one of the most common question is around what host lifecycle operations can be performed after an environment has been imported into VCF.
