Back Up Iphone to new Mac

I am in the process of selling my mac desktop. I've only ever sync'd and backed up my iphone on this mac. I'm not concerned about losing music or photos because they're all either on my macbook or in the cloud. I"m more concerned with losing texts and contacts. Can I plug my iphone into my macbook, make sure auto sync is off and back it up to the new macbook?
