This topic provides upgrade scenarios for Tanzu Kubernetes Grid Integrated Edition (TKGI) environments that are upgraded from v1.11 to v1.12 on vSphere.

Overview

When you upgrade TKGI on vSphere, you might also upgrade vSphere and, if you are using it, NSX‑T.

TKGI, NSX‑T, and vSphere upgrades depend on each other. Some combinations also require upgrading Ops Manager or TKGI-provisioned Kubernetes clusters.

For any combination of upgrades that you perform, you must follow the upgrade order described in this topic.

TKGI on vSphere with NSX‑T Networking

When upgrading a TKGI environment on vSphere with NSX‑T networking, you can choose to upgrade any of the following:

  • TKGI only, optionally including Kubernetes clusters
  • TKGI, Kubernetes clusters, and NSX‑T
  • TKGI, Kubernetes clusters, NSX‑T, and vSphere

Note: When upgrading TKGI to mitigate the Apache Log4j vulnerability you must also upgrade all TKGI clusters.

For more information, see below:
