I don't want to get into the details of Expedition and its history so I'll skip that.
In regard to your base config file, take the new 3060, remove all VWIRE references, then save the config and export it as a base file XML. Note, it should be the version you want to use , i.e. 6, 7 or 8.
When you are done with all your migration manipulations in Expedition, then you need to set the Base config. This is where you go and import the base config and then merge the changes into the base config. You can also attach to the new 3060 and add it to Expedition as a "Device". Once that is done successfully, you can use the "Device" as your base config.
Hope that helps.
