Migrating a Stateful Application with Persistent Volumes on VKS (TKGI to VKS Series, Part 19)
Moving a 500 GB PostgreSQL volume from TKGI to VKS with Velero snapshot data movement, a storage class mapping that stops the PVC hanging, and a checkpoint hook that stops the database coming back corrupt.
-
Migrating a Stateless Application End to End on VKS (TKGI to VKS Series, Part 18)
Move a stateless service from TKGI to VKS with Velero, then fix the two things that break on VCF 9, Pod Security admission and image pull secrets, before you touch DNS.
-
Velero on Source and Target, the Migration Toolchain (TKGI to VKS Series, Part 17)
Velero is the one toolchain that spans both estates in a TKGI to VKS migration. Install it on the source TKGI cluster and the target VKS cluster, wire shared S3 object storage, and prove a backup restores before any workload moves.
-
Identity, RBAC and Harbor on VKS (TKGI to VKS Series, Part 15)
How to replace TKGI UAA with vCenter SSO, map old LDAP groups to vSphere Namespace roles, grant developers scoped RBAC, and install Harbor as a Supervisor Service on your first VKS cluster.
-
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.
-
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.
