Just a quick tip, if you are also relatively new to Linux, don't rush with the updates. Some will at some point break something. Do you want to be the first one to experience it?
Lees you know, less you are comfortable, longer you wait with the updates.
Lower pool number in first msg "No issues, everything went smoothly", longer you wait with your update. (btw, this time pool numbers are one of the best.)
See what kind of problems others had. What was the fix? Once you gather all this intel, then you proceed
Also, because of the nature of rolling distributions, have a backup done at least every so often!
