First, compare the two files, foo and foo.new... They may be the same, depending what the file is for and whether anything has changed. Depending on what the file(s) are for, you may choose to keep the old config file (foo) if you have maybe done some work customizing it, or you may choose to use the foo.new file. Or maybe there is only minimal difference between the two, and you can just take the necessary stuff from the .new file and put it into the original one.
**Most** of the time, when I have had this happen, I end up keeping my old files. HOWEVER I have never upgraded, I started out with Slack 11.
You can always rename the original one foo.OLD, and then rename the foo.NEW file to foo, and see what happens, if you are totally unsure what the file does.
