Updating from 2.224

PI2 and HiFiBerry Digi+.
Like others I have found my self stuck on an old release and the the ‘Check Updates’ doesn’t do anything. It seems a re-flash with the current version is required.
My question is:
Is there an easy way of copying and saving all the settings and scripts (I have added some python script to pass the song title to my PreAmp display) so it can added to the new version?
Paper and pencil seems a bit old fashioned!
