When you rename a table, the grants, partitions, indexes, triggers and constraints are not affected.
However, references to the table are not automatically updated - so you'll need to fix any synonyms, as well as any code (e.g. in views, stored procedures, packages, and triggers on other tables) that refers to the table directly.
