FAQ How do I upgrade Eclipse?
Upgrading Existing Eclipse Features
Run the Update Manager, using
Help > Software Updates > Find and Install... > Search for updates of the currently installed features
The Update Manager will visit the Update site(s) for all your installed features/plugins and offer updates if any exist.
However, as of Eclipse 3.2, it is NOT possible to upgrade the Eclipse platform itself, only its features. So, you could for example upgrade the CVS feature or the PDE feature from 3.2.0 to 3.2.1, but not eclipse.exe itself.
If you want to upgrade to stable stream releases or even nightly builds, you have to live on the edge. Download a new build from the Eclipse download Web site (http://www.eclipse.org/downloads) and unzip it in a new directory. We strongly recommend against unzipping over your existing Eclipse version as unexpected side effects may occur, including (but not limited to): nausea, vomitting, shortness of breath, corrupt installation.
Complete upgrade instructions are always included in the Eclipse readme_eclipse.html file included with every build in the readme directory.
Upgrading Other Features
Upgrading other features (like CDT, PDT, WTP...) can be done without the need to download a new platform binary, but because many projects align very closely (eg., the Eclipse 3.2 / Callisto or Eclipse 3.3 / Europa release trains) you will likely need to upgrade the Eclipse platform as well.
