This might not be quite as simple as mattrix suggested, depending on which exact version you are using. Yes, if it uses iLok and the license is on the iLok, then you have no worries. If the license is left in the cloud, that is probably also fine, but for myself, I will not use cloud iLok except in an emergency. The last one is Pro Tools Intro, which is authorized on the computer. That version MIGHT need to be deactivated(hopefully a moderator can comment), but that version includes several authorizations(I think its 5)
