Moving tables to new tablespace needs temp space or any kind of addictional space? (Oracle 11g) I've been trying to search for this info on oracle documents but they just don't talk about it.

I need to move about 2TB of different tables from 3 different tablespaces to a new tablespace (encrypted one). Do I need to have temp space to do it (2TB)?
Moving a table does not use the temporary tablespace.
