Replace SigNoZ during upgrade

Warning: This permanently deletes observability data​

Upgrading an existing OBaaS release to this optional 2.1.1 patch release replaces SigNoZ rather than migrating it. The procedure permanently deletes all existing SigNoZ telemetry, dashboards, users, alerts, ClickHouse data, and ZooKeeper data. It does not affect the application database or other OBaaS services.

This release has no in-place or data-preserving SigNoZ upgrade path.

If the destructive-replace settings are omitted from an existing-release upgrade, Helm fails before changing any OBaaS resources. Users who require a data-preserving upgrade are encouraged to follow SigNoZ's own documentation; that path is not supported by OBaaS 2.1.1.

Upgrade command​

Use the complete values file for the installed release and explicitly acknowledge data loss:

helm upgrade <app-release> helm/infra-charts/obaas \
  -n <application-namespace> \
  --timeout 30m \
  -f <customer-values-file> \
  --set signozUpgrade.mode=destructive-replace \
  --set signozUpgrade.confirmDataLoss=true

Fresh installations do not need these settings.
