There are many ways to clone one phone to another. Assuming that you set the new phone up with the same account details as the old one, then you apps will appear under "My Apps and Games" in the play store, in the Library tab, from where you can then simply download and install them. The most hassle-free way though, would be to back up you old phone to Google Drive, and restore it on the new phone - this will also allow you to easily transfer your contacts, etc.
