-As a warning, this upgrade requires specs to be retrieved for all connectors that currently exist in your database. So, if specs cannot be retrieved for any of your connector images, server startup will fail. In this case you must either fix the image so that spec retrieval is successful, or set the `VERSION_0_32_0_FORCE_UPGRADE` environment variable to `true`, which will cause the server to delete any connectors for which specs cannot be retrieved, as well as any connections built on top of them.
+As a warning, this upgrade requires specs to be retrieved for all connectors that currently exist in your database. So, if specs cannot be retrieved for any of your connector images, server startup will fail. If you use custom connectors, this upgrade requires your all of your connector specs to be retrievable from the node running Airbyte, or Airbyte will fail on startup. If the specs are not retrievable, you need to fix this before proceeding. Alternatively, you could delete the custom connector definitions from Airbyte upon upgrade by setting the VERSION_0_32_0_FORCE_UPGRADE environment variable to true. Steps to specifically check out v.32.0 and details around this breaking change can be found here.
