First VKS Cluster on VCF 9, Namespaces, Cluster Classes and Node Pools (TKGI to VKS Series, Part 14)
Standing up the first VKS cluster the dev wave lands on: create the vSphere Namespace, bind resources, pick a Cluster Class and Tanzu Kubernetes release, apply the manifest, size node pools, and verify with kubectl.

Supervisor Networking on VCF 9, NSX VPCs and Load Balancer Choices (TKGI to VKS Series, Part 13)
Your vSphere Supervisor load balancer is a one-way door on VCF 9. Here is how Foundation LB, NSX LB and Avi compare across NSX VPC networking when you move a TKGI estate to VKS.
-
Preparing VCF 9 and Enabling the vSphere Supervisor (TKGI to VKS Series, Part 12)
The first hands-on step of the migration: stand up the vSphere Supervisor on VCF 9 beside your TKGI estate, with the design calls, the exact commands, and the failures that stall activation.

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.
-
Identity, RBAC and Secrets Assessment for TKGI to VKS (TKGI to VKS Series, Part 9)
Identity does not ride along with a Velero backup. Assess TKGI UAA, LDAP and RBAC against vCenter SSO, Pinniped and VKS namespaces, and reseal secrets before you cut over.
-
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.
-
Networking Assessment for TKGI to VKS, NSX-T vs NSX VPC (TKGI to VKS Series, Part 7)
Assess your TKGI NSX-T pod networking against the NSX VPC and Antrea model VKS uses on VCF 9, with a construct by construct mapping table and the addressing math that decides the target design.
-
Application Assessment and Migration Waves for TKGI to VKS (TKGI to VKS Series, Part 6)
Assess every TKGI application, pick between a Velero restore and a pipeline redeploy, and sort your workloads into migration waves that reach VKS on VCF 9 without a big-bang cutover.
-
Inventorying the TKGI Estate Before a VKS Migration (TKGI to VKS Series, Part 5)
A read only, three pass inventory of a TKGI 1.18 estate, TKGI CLI for clusters, BOSH for the VMs, kubectl for workloads and storage, and why the persistent volumes, not the cluster count, decide your migration schedule.
-
TKGI to VKS Migration Business Case and Phased Timeline (TKGI to VKS Series, Part 4)
TKGI is on a lifecycle clock and VCF 9 is the destination. Here is the business case, the drivers that set your real deadline, and a phased timeline you can hand a budget owner.
-
TKGI to VKS Is a Migration, Not an Upgrade (TKGI to VKS Series, Part 3)
TKGI and VKS differ at the control plane, machine lifecycle, network and identity, so there is no in place upgrade path. Here is why this move is a migration, and what that word changes about budget, risk and rollback.
