How to access my old icloud information?

I had an iphone and had it replaced. The store told me not to restore my information but start over. The information is in the icloud backup on my phone but I don't know how to access it. It shows 2 icloud backups and I want to access the first one to save the information I had from the first phone.

You need to log into your old iCloud account on your new iPhone and sync it with your new phone and all old information will reappear, such as pictures, contacts etc
