Few table names of database are already renamed/replaced in magento 2 database structure. like

'core_website' replaced with 'store_website' along with its structure.

Few fields of tables are removed in magento 2 database structure like -

The ‘customer_entity’, ‘customer_address_entity ‘tables removed the ‘entity_type_id’, ‘attribute_set_id’ fields
