So in a uc migration project,
we have a fivetran connection which handles most of the etl processes and writes data into hive metastore. 

we have migrated the schemas related to fivetran in UC. 
The workspace where fivetran was running had default catalog as hive metastore , we have updated it to our uc catalog and the compute which runs the fivetran related etl work we have specified the default catalog to our uc catalog.

Do we have to make any changes from fivetran side as well? Not aware about it. Or that''s all we need to do to handle this migration.
