Decommissioning TKGI and Ops Manager After the VKS Migration (TKGI to VKS Series, Part 26)
TKGI is idle and VKS carries production, so now you retire the old platform. A step by step teardown of TKGI clusters, NSX-T objects, BOSH and Ops Manager, with the point of no return marked and the capacity handed back to VCF 9.

Day-2 Operations on VKS, Lifecycle, Upgrades and Scaling vs BOSH (TKGI to VKS Series, Part 24)
After the cutover, Day-2 on VKS replaces BOSH and Ops Manager with a declarative model. Here is how to upgrade Kubernetes versions, scale node pools, and roll back safely, with the commands that map to your old TKGI habits.

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.

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.
-
TKGI vs VKS Architecture Compared, Component by Component (TKGI to VKS Series, Part 2)
TKGI and VKS set side by side, control plane, cluster lifecycle, networking, storage and identity, so the architecture gap behind the migration is concrete before you design the VCF 9 target.

What VKS Is and Why TKGI Is Winding Down (TKGI to VKS Series, Part 1)
There is no upgrade path from TKGI to VKS. Part 1 explains what the vSphere Kubernetes Service is, why the old platform is winding down, and why the move is a migration you plan rather than a patch you apply.
