That is a heck of a short turn-around time (about one month) to upgrade the entire LTS install base. 12.04 is on LTS through late 2017 and 14.04 is on LTS through late 2019. I think it&#x27;s reasonable to expect servers running those operating systems to stay in the wild through those time frames. I may be in the minority but I skipped 12.04 completely and upgraded my 10.04 servers to 14.04 just as 10.04 was going off LTS. This could get ugly!
