How to sync my iphone to another computer? - 1

I want to sync my phone to my laptop. It's normally synced to the desktop and it's been like that for years. Everything is on there. But that ran out of space. I have on my laptop all my songs purchased along with my apps. I've heard about having to change this ID thingy I don't wanna do that. I have a lot of data and stuff on my phone that icannot loose. Is there anyway to sync it without loosing everything? And then when we free up the desktop can I plug it in there with no problem? I have an iphone 5 newest iTunes version on my laptop and the newest update on my phone. Does authorizing iTunes to my laptop let me sync it? I have it authorized. Some how when I signed in all my apps and music that I purchased were there and I'm just downloading all of them now. Is that a sign that I can just go and do it?

You can deauthorise the other itunes and authorise it for the new one, it won't delete anything, I have done this for my iPhone
