If you are running Airbyte on Kubernetes, you will need to use one of the two processes defined [here](https://docs.airbyte.com/operator-guides/upgrading-airbyte#upgrading-on-k8s-0270-alpha-and-above) that differ based on your Airbyte version [source](https://docs.airbyte.com/operator-guides/upgrading-airbyte). 3. Connector Upgrades: When Airbyte is upgraded, it will attempt to upgrade some connector versions. If a connector is not used, it will be upgraded to the latest version. If a connector is used, it will NOT be upgraded to avoid disrupting working workflows. If you want to upgrade a connector, do so in the settings page in the webapp [source](https://docs.airbyte.com/operator-guides/upgrading-airbyte). 4. Data Loss: As per the information available, there's no mention of losing existing syncs when updating. However, it's always a good practice to backup your data before performing any major updates. 5. Support: If you need help from the Airbyte team for your upgrades, they offer premium support to their open-source users. You can [talk to their team](https://airbyte.com/talk-to-sales-premium-support) to get access to it [source](https://docs.airbyte.com/operator-guides/upgrading-airbyte). Remember to always follow the official [upgrade guide](https://docs.airbyte.com/operator-guides/upgrading-airbyte) to ensure a smooth upgrade process.
