I use this site to share what I learn while building, upgrading, troubleshooting, and automating systems in a VCF Holodeck lab. The posts cover the products, tools, failures, fixes, workarounds, and experiments I run into along the way, including the details behind each workaround.
Upgrading VCF Telemetry to 9.1.1 Step by Step
With VCF 9.1.1 released on September 3, 2026, I continued patching the management services in my lab. In this post I will go over upgrading VCF Telemetry from 9.1.0.0 to 9.1.1.0 through VCF Operations. The VCF 9.1.1 release notes are the source for the release scope, upgrade sequence, dependencies, and known issues. The VCF Operations 9.1.1 release notes list the Telemetry target build as 25671600. Telemetry is a VCF management service hosted by the VCF services runtime. The supported lifecycle workflow is Build -> Lifecycle -> VCF Management -> Upgrade. This walkthrough covers one 9.1.0.x to 9.1.1 maintenance upgrade. If you are coming from an older VCF or Aria release, follow the applicable VCF upgrade procedure first. ...
Upgrading VCF Real-Time Metrics Store to 9.1.1 Step by Step
With VCF 9.1.1 released on September 3, 2026, I continued patching the management services in my lab.

It is separate from the Real-Time Metrics component, even though both appear in the same VCF Management list. The supported lifecycle workflow is Build -> Lifecycle -> VCF Management -> Upgrade. This walkthrough covers a 9.1.0.x to 9.1.1 maintenance patch; an environment coming from an older VCF or Aria release should follow the applicable VCF upgrade procedure first. ...

Upgrading VCF Operations to 9.1.1 Using a .PAK File
With the release of VMware Cloud Foundation 9.1.1 on September 3, 2026, I wanted to get my VCF Operations lab upgraded. This is a maintenance release focused mostly on supportability improvements. The VCF 9.1.1 release notes can be found here, and the VCF Operations release notes are here. In this post I will go over upgrading VCF Operations from 9.1.0.0400 to 9.1.1 using the upgrade PAK file.

Updating ESXi with the Authenticated Broadcom Depot or an Offline Bundle
This is the corrected follow-up to my earlier ESXi command-line upgrade articles. The shared public VMware host-update depot used in those examples is no longer valid. Broadcom now uses customer-specific authenticated download URLs, and its current standalone command-line procedure documents an offline depot ZIP with esxcli software profile update. The procedure and release information below were reviewed on August 25, 2026. Reopen the linked Broadcom articles during every change: depot authentication, entitlements, available profiles, release builds and support status can change. ...
Safely Removing an SDDC Manager-Deployed NSX Edge Cluster from VCF
This is the corrected follow-up to my older article about simplifying NSX Edge removal in VCF. The most important correction is that the Edge Cluster Deployment Removal Tool does not preserve everything attached to an Edge cluster. Broadcom requires added dependencies to be removed or disconnected before the cleaner runs. The procedure below is based on Broadcom KB 316110, reviewed on August 25, 2026. Always reopen the KB before a change because the attachment, checksum, prerequisites, and supported releases can change. ...
VMSA-2025-0004: Current Remediation and Fixed Versions
Broadcom published VMSA-2025-0004 on March 4, 2025, for three vulnerabilities affecting VMware ESXi and related desktop and cloud products. Fixed versions are available, and the advisory lists no workarounds for any of the three vulnerabilities. The practical response is therefore straightforward: identify every affected product, move it to a fixed or later supported build using its supported update method, and verify the resulting build. Access restrictions and monitoring remain useful defense-in-depth controls, but they do not replace the update. ...
