Migrating from Existing Iceberg Catalogs

There are two ways to migrate an existing Iceberg catalog to Polaris:

1. Using the Iceberg Catalog Migrator tool: A command-line tool to migrate Iceberg tables from one Iceberg catalog to another. This tool works with any existing Iceberg catalog including Polaris.
2. Using the Polaris Synchronizer tool: A tool to migrate entities from one Polaris instance to another. This tool is specific to Polaris.
