To upgrade your Airbyte instance, you can follow the steps outlined in the [Airbyte documentation](
https://docs.airbyte.com/operator-guides/upgrading-airbyte). Here's a brief overview: 1. First, you need to determine if you need to run the upgrade process. This is necessary if there are new features or bug fixes in the newer version that you want to use. 2. The upgrade process requires temporarily turning off Airbyte. 3. 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. 4. For your custom connectors, you might need to manually update them to ensure compatibility with the new Airbyte version. This could involve updating the version in the Dockerfile and the metadata.yaml file of the connector, as mentioned in the [Connector Development documentation](
https://docs.airbyte.com/connector-development). 5. 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](
