3.5 Updating Your Installation
You can update your installation of Eclipse, EMF, and OSATE by utilizing the Eclipse update manager. You can invoke it with the menu entry “Help/Software Updates” and then “Find and install”.  Be sure you have included the OSATE update site for OSATE updates (see section 3.4) and the Eclipse update site for Eclipse and EMF updates.
You can also update your installation by downloading the appropriate zip files and unzipping them into your installation (See “Installing into an existing Eclipse Installation” in section 3.2).
Be sure to read section 4.1.6 on “How to Manage Your Eclipse/OSATE Workspaces” to facilitate reinstallation of Eclipse & OSATE without losing your projects, allowing for backup of your Eclipse/OSATE workspaces, and to manage your projects in the workspaces through a version control system.
