Re-organize Customers with Multiple Subsidiaries

If we need to remove some subsidiaries in netsuite, we will have to delete and update transactions, entities, and general ledger (GL) accounts related to those subsidiaries. Deletion of these items can be done, but there may be customers who have connections with multiple subsidiaries. In such cases, updating these customers individually will be time-consuming. For example, if we edit and update each customer, it will take a considerable amount of time. How can we efficiently update these customers?
