Step 1
Go to Help ---> Install New Software...
Step 2 Try to find "http://download.eclipse.org/webtools/updates" under work with drop down. If you find then select and install all the available updates.
If you can not find then click on Add -> Add Repository. Name: Eclipse Webtools Location: http://download.eclipse.org/webtools/updates Select all available updates and Install them.
Visit http://download.eclipse.org/webtools/updates/ for more details.
Add the update URL to your available sites:
Window > Preferences > Install/Update > Available Software Sites > Add...
Name: Oxygen
Location: http://download.eclipse.org/releases/oxygen/
Then tell Eclipse to look for updates: Help > Check for updates.
After the installation, Eclipse will restart and show the old splash screen. Next time you manually stop/start Eclipse it will correctly show the correct splash screen.
You can simply download the newer version, then use "File -> Import -> Install -> From Existing Installation" to add all the plugins you had in your previous installation.
Here's a link describing the whole process in details (it says "on Mac Os X", however it should work for other systems as well):
