XF 1.5 Importing and Admin CP Settings

Hi all, is there a way to just save or export any setting changes made in the Admin CP.

the scenario is: i have a xenforo install that i've imported a vB4 forum into, we now want to change/tweak may of the default settings in admin CP, at some point in the future i want to cut over from the vB4 live forum to xenforo, however as far as i can tell this needs a clean db for the import, so that means i'd have to re-do all the settings we're changing now, hence is there any way to save those settings and then reapply them after the final cut over import? i could do without having to document everything then go through one by one adding stuff back... if that makes any sense?
