Dude Beta8 upgrade path

has anyone figured out a fool proof way to upgrade from beta 7 to beta 8? I’d love to get some of the new features, however i don’t want to redraw and enter my entire network. I’m getting the following problems

do you want to upgrade to 3.07 on startup
can’t connect to local server
program loses connection to local server when importing a 3.07 backup
after import and reconnect labels, and graphics are not there, just green squares, and links
i get a debug error and completely program crash when trying to modify any devices that were imported.

Anyone got a way around this?
