upgrading GoLive to Dreamweaver

I just upgraded to Dreamweaver from GoLive. The Dreamweaver readme file tells
me to place the included gl2dw folder into the GoLive "extend scripts" folder
in order to get Dreamweaver to "see" my old golive file structures. OK I did
that, then checked the script in GoLive. When i restart GoLive, I get the
message that GL2DW only runs on GoLive 8 or better. My version is 7.0.2. So it
doesn't work.

Can someone explain what gl2dw is supposed to do, and what I may need to do by
hand, since clearly, this script is not going work for me? I seem to intuit OK
how everything works in Dreamweaver., especially after viewing the video
lessons. I got the file box to show my hard drive's website folder structure,
and then set up the remote file structure to show my ftp site OK. So is that
what the script does? I hate to be missing something essential, and hit a brick
wall without knowing what the solution is.
