Tbc ptr doubt

Hello everyone. I have a silly question to ask y'all. Plz don't get pissed for asking such a question. But tmrw the ptr realm will be out right? So if I download tbc for the ptr realm.... I won't have to download it again later for the actual game right?( like after the ptr is over)

It's a regular TBC client. Should be patch 2.4.3 as far as I know. PTR will have the same patch as the real realm so you won't have to download the client again.
