Updating your EclipseME installation
Eclipse implements a versioning system that allows you to update features and plugins without having to first remove the older versions. As a result, the process of upgrading to a new version of EclipseME is extremely easy.
From the Eclipse Help menu, select Software Updates and then Find and install...
You will be presented with the following dialog:

Select the Search for new features to install
radio button.
Press Next.
The update site you previously configured will be listed in the
Install dialog.

Ensure that there is a check next to the EclipseME update site, then
press Next.
From this point, the process is identical to the original installation procedure outlined above.
Note that updating EclipseME via the Search for updates of currently installed features does not work at this time. You need to follow the procedure above to update directly from the SourceForge site. We anticipate correcting this in the future.
The process of upgrading is identical to the process of initial installation. Simply download the new archive site file and go through the installation process using that file. If you wish, before upgrading using the new file, you may use the Remove button to remove the old archive file from the installer.
