will i have problems activating new PS4 as primary

hi, so i just upgraded to a PS4 pro, so deactivated my original PS4 as primary and activated the new PS4 pro as primary. Problem is, my PS4 Pro is acting up and i have to return it, so will i be ok deactivating this one and then activating another PS4 Pro as primary in such a short term ? I know theres some 6 month rules but i dont know the details 100%
