Attention Iron Bank Customers: On March 27, 2025, we are moving SBOM artifacts from the Anchore Scan job to the Build job to streamline the container hardening pipeline. If you currently download SBOMs from the Anchore Scan job, you can still get them from the Build job and from other sources, including IBFE and image attestations.
# Upgrading from the Istio Operator to Helm based Istio
### *The new service mesh is BETA in Big Bang 2.x and is planned to be completely stable in 3.0!*
### *The new Istio Helm packages are BETA in Big Bang 2.x and will be stable in 3.0*
### Step 1 : Remove Istio from your deployment
Before upgrading to version 3.0 of Big Bang with the new Helm-based Istio packages, we first need to disable Istio and Istio's Operator packages in our 2.x deployment of Big Bang. We do this by disabling the two obsolete [Istio packages in our Gitops configuration](https://repo1.dso.mil/kipten/template/-/blob/main/package-strategy/configmap.yaml?ref_type=heads#L18-22).
