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 Mars 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.

I don't think updating from Update Site will update the eclipse.ini file: you need to fix it.

-startup
plugins/org.eclipse.equinox.launcher_1.4.0.v20161219-1356.jar
--launcher.library    plugins/org.eclipse.equinox.launcher.win32.win32.x86_64_1.1.500.v20170531-1133

However, if you simply want to keep your preferences and your plugin, I suggest you to use Eclipse for that:

In Oxygen.1 (or the updated Eclipse), you can install feature/plugins

  1. using an existing installation (go to File > Import then select *Install > From Existing Installation)
  2. using an exported software item (go to File > Import then select *Install > Install Software Items from File)

For the second option, you need to export it first on the previous Eclipse using File > Export > Install > Installed Software Items to File.

Note: the Eclipse directory store little configuration (at least, it store the known workspaces/update site). This link here might be of interest.
