Diggs,
Transferring the Configuration Tool to another Windows Based PC is not a problem, but the login and password is best re-entered manually.
Install the Configuration Tool using the normal installation program, then save from the old PC the "Clients" sub-directory and if you have saved any templates and/or third party XML files not supplied by B&O then also copy over the "ThirdParties" and "TemplateZones" subdirectory and their contents to the new PC
