Upgrade notes

Users must migrate their old iam-config ConfigMap created manually to the TokenIssuer section of the install API. The structure is mostly the same with only the signingkeypath field changing to signingKey. See these examples for more information.

Because of the Istio control plane upgrade, the minimum Kubernetes version required to run the TSB control plane is 1.16. Also, some attributes change its location within the IstioOperator resource so you will need to manually remove the conflicting attributes. You can use the following command to that end.

kubectl patch iop -n istio-system tsb-istiocontrolplane --type='json' -p='[
{"op": "remove", "path": "/spec/values/global/certificates"},
{"op": "remove", "path": "/spec/values/global/disablePolicyChecks"}

As of TSB 0.9.0, tsbd is configured by default to work with v2 API. If you had an overlay in your ControlPlane resource to override the default v1 and use v2, you will need to remove that overlay as it will cause the TSB operator to fail rendering such overlay (as the flags it refers to may no longer exist).

Due to changes in the SkyWalking templates and index and template naming, it is imperative to delete the SkyWalking related Elasticsearch indexes and templates.
