A search led me to this result. I hope it works out for you. I haven't run V9 for quite a while and have never dealt with .GE3 files.
Actually this is probably a better solution...Hit Alt-c,
converts all old Ge3 and even old Ge0!!
See attached "VB Script". I don't know how to run this in V9 but at least you're off to a good start now...Run this in V9 to convert directories containing GE3 files to MC9s.
A little more reading reveals that you need to upgrade to V9.1 before running a VB Script.
There must be more info in the help files...
