Problems restoring configuration from old firewall

 I've bought a ne SG310 - Rev.2, and im trying to move my configuration from my SG230. Both running 9.602-3. 

When I login to 310 first time, I gives me the option to restore a configuration. When I do that, the webinterface hangs, my Ping is still running. Tried waiting up to 15 minutes with no luck, tried rebooting, and the IP address has not changed and in the console I types All configuration is done with WebAdmin. Go to https://192.168.0.1:4444

But the WebAdmin does not work, just gives me a Err_connection_refused in chrome, also Safari does not work. The only way to progress is to factory reset the device. I've tried restoring by WebIF, CommandLine and by putting the ABF on a USB stik. 

No matter what I tri, the problem is the same. Tried several different backups, but always used the Function Unique site data when creating the Backup. Any pointers ? 

Thanks in advance
