Moving to Austria - Requirements (Vienna)

Hello everyone,
My Family and I will be moving to Austria in April. We will be relocating perminantly. My Wife and Son are both Austrian however i am Portuguese. As i understand it since I am from a member state i can move to Austria without a problem however if i want to relocate permanently i will need to apply for permanent residency. I already have a job and accommodation there in Vienna. Is there anything else i would need to do ? I am assuming my wife and son don't need anything since they are Austrian ?
