Decommissioning TKGI and Ops Manager, and What Comes Next (TKGI to OpenShift Series, Part 26)
A ten step teardown runbook for retiring a TKGI estate after the OpenShift cutover, covering cluster deletion, the TKGI tile, Ops Manager, BOSH, and the NSX-T and vSphere objects that survive every documented step.

OpenShift Projects, Quotas and MachineSet Scaling (TKGI to OpenShift Series, Part 14)
TKGI gave every team a cluster and a plan. OpenShift gives them a Project, a quota and a share of one node pool. Here is the runbook that makes that swap, with the project request template, the vSphere MachineSet, the autoscaler pair and the quota rejection that took out a whole migration wave.

Installing OpenShift 4 on vSphere, IPI and UPI Compared (TKGI to OpenShift Series, Part 12)
IPI or UPI for the first OpenShift cluster beside your TKGI estate. A working install-config for vSphere, the three DNS records that decide the install, and the bootstrap failure that costs most teams two attempts.
-
Target Reference Architecture, OpenShift 4 on vSphere (TKGI to OpenShift Series, Part 11)
A concrete OpenShift 4 target for our reference TKGI estate: two clusters instead of three, three vSphere failure domains declared on day zero, and a mapping table from every TKGI component to whatever replaces it.
-
Storage and Data Assessment, vSphere CSI and Persistent Volumes (TKGI to OpenShift Series, Part 9)
A working method for inventorying persistent volumes on a TKGI estate, mapping storage classes onto OpenShift 4 vSphere CSI, and sizing restore windows before wave one starts. Includes the RWX trap and the storage class rename that leaves PVCs Pending forever.

Target Reference Architecture for VKS on VCF 9 (TKGI to VKS Series, Part 11)
A VKS target on VCF 9 resolves into five layers, and the workload network you pick decides your load balancer before you build. Includes the TKGI to VKS component mapping, the load balancer decision table, and reference cluster sizing.

Multi-Tenancy and Self-Service from TKGI Plans to vSphere Namespaces (TKGI to VKS Series, Part 10)
On TKGI a tenant meant a whole cluster. On VKS it means a vSphere Namespace with its own quota, roles and network. Here is how to map TKGI plans and self-service onto the namespace model without recreating cluster sprawl.
-
Storage and Data Assessment for TKGI to VKS, vSphere CSI and Persistent Volumes (TKGI to VKS Series, Part 8)
A PVC that reads Bound is not proof the data moved. This part assesses every persistent volume in a TKGI estate by its backing First Class Disk and storage policy, then maps each one to a VKS target and a migration method that fits its size and downtime budget.

How to break into a VMware career: certs, interviews and your first job (VMware for Beginners, Part 18)
A practical, no-fluff guide for freshers on breaking into a VMware career in 2026: which certification to start with, the interview questions that trip people up, and what actually gets you hired.

Where VMware fits in 2026: still everywhere, now subscription-only (VMware for Beginners, Part 16)
VMware in 2026 under Broadcom: the same technology, a shorter product list, subscription and per-core pricing, and an honest look at where it still beats Proxmox, Nutanix and Hyper-V for freshers.

Common VMware mistakes beginners make, and how to avoid them (VMware for Beginners, Part 15)
The mistakes that trip up almost every new VMware admin: oversizing vCPUs, treating snapshots as backups, filling datastores, and skipping VMware Tools. Here is why each one bites, with real numbers and a home-lab task to see it for yourself.

VMware backups vs snapshots: what freshers get wrong (VMware for Beginners, Part 14)
A snapshot is a save-point that depends on the original VM; a backup is an independent copy stored somewhere else. Mix them up and you can lose data. Here is the difference, in plain English, with a home-lab task and a real interview question.
