Thread: Upgrading from 11.4 to 12.2 on a server

  1. #1

    Default Upgrading from 11.4 to 12.2 on a server

    The VPS host I am going to move to only offers opensuse 11.4, and I would like to upgrade it to 12.2 since 11.4 is EOL'ed, or soon to be?

    Should I go 11.4->12.1->12.2 or can I just go straight to 12.2?

    Personally, I've experienced nothing but problems when trying to upgrade distros between versions, from Fedora to CentOS to Ubuntu to, yes, openSUSE. I have successfully upgraded several systems, openSUSE included, but it has always introduced problems that then need to be tracked down. Every single time, without fail, it has been faster to simply back up the important directories (/home, /etc, etc) and re-install from scratch. It usually only takes an hour or two to get everything back up and running like normal, compared to the 6+ hours it usually takes to track down and fix the bugs introduced during an in-place upgrade.

    Last time I tried to upgrade openSUSE it was 12.1 to 12.2. Halfway through the upgrade "konsole" was updated and it literally crashed every konsole I had open, including the one that was doing the upgrade. Talk about a royal PITA to try to recover from...and even once I got 12.2 installed completely, I still had endless driver problems. I ended up just wiping it any installing 12.2 from scratch in the end.

    Just my opinion.

    Just for your information, openSUSE 11.4 will be supported by the Evergreen
    project until Juy 2014. See:

    http://en.opensuse.org/Evergreen

    AFAIK, Evergreen provides only security updates, not new applications.

    11.4 has already reached EOL
    but you may opt to use it until July 2014

    The first one is the way to go

    This probably would be the best approach for you because you need to jump multiple version.
    You may need to be careful as there are changes related to

    I did the first on my systems here; if you have just the standard repos
    set up, then that's pretty painless. If you've added a bunch of stuff
    from other repos, that can lead to trouble.

    Evergreen or Tumbleweed might be an option for you to look at.

    But before doing anything as major as an upgrade, back up your critical
    data and configuration information. Just in case.

    others here may correct me if i'm wrong, but i kinda doubt if your
    host will have put in place the tools/permissions needed to allow you
    to upgrade the system from 11.4 to anything else.

    have you asked the host if that is even possible?

    if it is possible they could try following one of these recommended
    paths:
    http://tinyurl.com/35p966c
    http://tinyurl.com/93uemsr
    both of which would require you to first fully update 11.4, then
    upgrade to 12.1, fully update it and finally upgrade to 12.2

    but, sure and read the parts like:

    - If for any reason the upgrade is interrupted (e.g: power outages,
    network disconnect) and the process can't continue, you could be left
    with a broken system

    - Be aware that in principle, this upgrade process is considered
    “best effort” only. This means that due to some third-party packages
    and the myriad of possible configurations, it is possible for some
    combinations to cause failure upon upgrade.

    - It is very important that all important data is backed up prior to
    beginning the upgrade process.

    - Before upgrading, copy the old configuration files to a separate
    medium (such as removable hard disk or USB flash drive) to secure the
    data [as a VPS user i doubt you have any access to the config files,
    so ??]

    - Depending on your customizations, some steps (or the entire upgrade
    procedure) may fail and you must resort to copying back your backup data.

    personally, i think you are better off either finding a host offering
    a supported version of Linux *or* do as i have done for over 10
    years: just use the operating system and user tools that the VPS
    hosting service offers..

    and, that generally will not be full root access to the OS...which is
    a hard requirement to update or upgrade..

    This is what I would prefer.

    Do a fresh installation of 12.2 while of course keeping those partitions, where application/users data is on, untouched. This last is often to be found here on the forums as the advice "while keeping the /home partition untouched". But for a system that has "serving" as it's main task, there are of course separate partitions for the "serving part" (web sites, mail boxes, centraly located files, ..... whatever the "server" is serving").

    To be able to test things, I would prefer to have a seperate partitiion where I can install the new openSUSE version on in a multi-boot situation with the existing version. Cross booting with all data in place (you could even mount all data partitions ro to protect it in the first tests) is then possible. Fall back is easy. Of course a full backup of the data before you start every test is a must.

    Ann extra bonus of this is then when you, during a test, mount the "other" system partition read-only, you can very easily check how configuration file in e.g. /etc look like on the "other" system.

    On normal machines, the available procedures are these:

    Online upgrade
    method

    Offline upgrade
    method


    Chapter 16. Upgrading the System and System Changes



    On a hosted environment, I don't know that you can upgrade the "machine".

    However, you also have Evergreen support for 11.4.

    With root permissions, a distro-upgrade would/should be possible.
