Understanding the effects of upgrading to Unity Catalog.

Hello, I have been trying to solidify my understanding of what changes occur after I upgrade my data to Unity Catalog. Our current ingestion process incrementally loads new data to tables in the hive metastore which are mounted to an s3 bucket. If I upgrade these tables to UC, will the daily incremental data also update in UC or is the data in UC just a 'moment in time' copy of my tables in the hive metatsore. Thanks in advance.
