How to upgrade new version of eclipse instead of using new downloaded package

I am looking for steps to upgrade my current eclipse version(Mars) to latest version(Oxygen) because I have been using Masr for past long time so that contains all the settings, plugins and all the histories so I would like to retain the same and also upgrade to new version.

Is this possible?

Note: It can be any type of eclipse for any kind of development like Java, C/C++, PHP, Javascript and Testers
