How do I update old project formats to work with the new version of gINT?

Note...I just installed the "converter version" 10.00.01.07, but I do not know the steps to open project, convert project, and save project as the latest version.  I assume there is no way to batch convert?  We literally about 1000 legacy projects that will need to get updated if we wish to keep the old data (which we do :-)

thanks!
