Is it possible to migrate data from one DLT pipeline to another?

Hi,

We have a DLT pipeline that has been running for a while with a Hive Metastore target that has stored billions of records. We'd like to move the data to a Unity Catalog. The documentation says "Existing pipelines that use the Hive metastore cannot be upgraded to use Unity Catalog. To migrate an existing pipeline that writes to Hive metastore, you must create a new pipeline and re-ingest data from the data source(s)." The problem is that the original data sources no longer exist, so we can't just start a new pipeline and get all the data. Is there any way to migrate/copy the data from the existing pipeline to a new one as the starting point for that pipeline, so it doesn't have to start from the beginning?
