How to upgrade Laravel 5.0.* to 5.2.* or later

My Application is built with Laravel version 5.0.35 and I want it to update to version 5.2.*

How can I do this?? Can I just replace '5.0.*' to '5.2.*' in composer.json file and then command composer update, will this work?? If not, then is there any way with which I can upgrade easily and automatically?? Please guide me step by step if possible...
