Based on the information provided in the knowledge sources, it appears that normalization and transformation operations are not supported for certain connections in Airbyte. This could be due to the specific source and destination connectors you are using, or the version of Airbyte you are running. For example, in one of the [Github issues](https://github.com/airbytehq/airbyte/issues/23398), a user reported that normalization and transformation operations were not supported for a connection using Hubspot as the source connector and S3 as the destination connector in Airbyte version 0.40.32. In another [discussion](https://github.com/airbytehq/airbyte/discussions/38168), it was mentioned that custom transformation and normalization were deprecated and Airbyte recommends using dbt with an orchestrator to run the job to your pipeline for post-transformations to your data. If you are facing this issue, it would be helpful to check the specific source and destination connectors you are using, and their respective versions. If the issue persists, consider raising an issue on the [Airbyte Github](https://github.com/airbytehq/airbyte/issues) or discussing it on the [Airbyte forum](https://discuss.airbyte.io/).

To upgrade your Airbyte platform to version 0.63.0, you can follow these steps: 1. Backup your data: Before starting the upgrade process, it's recommended to backup your data. This is to prevent any data loss in case something goes wrong during the upgrade process. 2. Pull the latest version of Airbyte: You can do this by running the following command in your terminal:

docker-compose pull

This command will fetch the latest version of Airbyte from Docker Hub. 3. Run the upgrade command: After pulling the latest version, you can upgrade Airbyte by running:
