So I'm in the process of upgrading my "SERVER" not desktop... There are 320 packages that can be updated I've installed systemback and created a restore point I'm currently running Ubuntu 14.4.4 LTS and I want to upgrade to 16.4.6 LTS my server has a lot of stuff on it, multiple websites, data etc... and if something fails such as causing down time i'm screwed.

I can't seem to find the "safest" solution for updating my Ubuntu server or should updating my ubuntu server not have any impact on my live data/sites..?

  1. is it safe to upgrade from 14.04.4 LTS to 16.04.6 LTS (i've taken a backup of the server)
  2. If anything goes wrong, can I use my restore point that I took in my 14.4 LTS (before upgrading) and revert back to 14.4 LTS after I have already installed 16.4 LTS?

or if you have any other suggestions I'd be happy to hear them.

Thank you! -Paul

  • Upgrades have been safe for me, but IMHO, it would be wise to test an upgrade first. 2. Yes, why else would make a snapshot?
