Do you need to upgrade your Hive tables and Views to Unity Catalog?
You have the below options available which you can select based on the requirements:
UCX: A command-line utility suite for comprehensive Unity Catalog migrations, ideal for large Hive metastore upgrades, supporting both managed and external tables with bulk migration options for advanced users comfortable with scripts.
Unity Catalog Upgrade Wizard: A visual tool for quickly upgrading Hive tables to Unity Catalog external tables, suitable for users preferring a GUI and featuring optional scheduled syncs for hybrid Hive-Unity Catalog setups.
SYNC SQL Command: A SQL-based approach to upgrade Hive tables to Unity Catalog external tables, ideal for SQL users needing scheduled syncs, though it requires CREATE TABLE CLONE for managed tables in Databricks storage.
CREATE TABLE CLONE SQL Command: A method for migrating Delta-format Hive managed tables to Unity Catalog managed tables, preserving metadata with simple syntax and preferred over CREATE TABLE AS SELECT for streamlined upgrades.
