@kapa.ai What is the latest Airbyte OSS version. We have an existing 1.4.0 OSS version installed via Help on K8 cluster with local port forwardig, how should we move about upgrading it to the latest oSS version?

Latest Airbyte OSS Version Based on the release notes, the latest Self-Managed Airbyte version is 2.2, released on August 10, 2026. [Self-Managed Release Notes] Upgrading from 1.4.0 to the Latest Version Since you're on 1.4.0 with Helm chart V1 on Kubernetes, your upgrade path has an important prerequisite: you must migrate to Helm chart V2, as V1 is no longer supported as of Airbyte v2.1.0. [Helm Chart V2 Upgrade] Here's the recommended upgrade path: Step 1: Backup Your Internal Postgres Database Since you're likely using Airbyte's internal Postgres (local setup), back it up first:

# Find your DB pod
kubectl get pods --all-namespaces | grep db

# Dump the database
kubectl exec -n airbyte -it airbyte-db-0 -- bash -c "pg_dump -U airbyte db-airbyte > /tmp/airbyte_backup.sql"

# Copy backup locally
kubectl cp airbyte/airbyte-db-0:/tmp/airbyte_backup.sql ./airbyte_backup.sql

[Helm Chart V2 Upgrade] Step 2: Add the Helm Chart V2 Repository Helm chart V2 uses a different repo URL (

/charts

) than V1 (

/helm-charts

):

helm repo add airbyte-v2 https://airbytehq.github.io/charts
helm repo update

[Helm Chart V2 Upgrade] Step 3: Uninstall the Old Helm Release > ⚠️ Do NOT delete the namespace — only uninstall the release.

helm uninstall airbyte -n airbyte

Step 4: Create a New values.yaml for V2 The V2 chart has a different configuration syntax. You'll need to create a new

values.yaml

compatible with V2. Refer to the migration guide for syntax changes. Step 5: Identify the Target Helm Chart Version

helm search repo airbyte-v2 --versions

This shows you which Helm chart version maps to which Airbyte app version. [Deploy Airbyte] Step 6: Reinstall Airbyte with V2 Chart

helm install airbyte airbyte-v2/airbyte \
  --namespace airbyte \
  --values ./values.yaml \
  --version <chart-version>   # e.g., the version corresponding to 2.2

Step 7: Resume Port Forwarding After installation, resume your local port forwarding:

kubectl -n airbyte port-forward deployment/airbyte-server 8080:8001

[Upgrading Airbyte] ⚠️ Key Notes • Airbyte 2.1 is marked as experimental — if stability is your primary concern, you may want to go directly to 2.2. [Airbyte 2.1 Release Notes] • Review the breaking changes list before upgrading, as jumping multiple versions may involve breaking changes. • During the upgrade, Airbyte will be temporarily unavailable. 👍 0 button 👎 0 button ℹ️ Tip: Mention @kapa.ai in the thread for follow-ups or DM the app for 1-to-1 help.
