Update from 11.4 to 12.3

[Prof. Filipe]

I have 11.4, 64 bit, evergreen. Now I'm downloading 12.3 and will soon
create the DVD of 12.3. Can I update directly from 11.4 evergreen to
12.3 or should I go first to 12.1 or something else?

[Elmer Wright]

No, I did the same, 114->123 directly by changing the repositories, then
update and reboot. Works fine, small things maybe needs reconfiguration,
but compared with a fresh new install is luxury.

i hate to disagree, but there are three recommended/supported paths
to upgrade...two of them only move one version at a time:
http://tinyurl.com/35p966c
http://tinyurl.com/93uemsr

another attempts to go more than one version at a time
http://tinyurl.com/7l4m2td

none of them are guaranteed to work, and even the one which says it
is possible to skip a version warns: "It is possible that a jump
across 3 or 4 versions can work, but there is no assurance. If you
want to try, make a full backup, get a comfortable chair, and go
ahead :-)"

so, the starting point of all of the recommended paths is a good backup.

however, my personal preference is to do none of those three
"upgrades" and instead save/copy all data to an off-machine location
and do a complete format, fresh install, system rebuild and data rejoin.

why? because i find the fresh install is less likely to have
stability problems AND considering the time it takes to run down all
the little problems an 'upgrade' usually includes, it is faster to do
it my way. ymmv

i also am loving 11.4 Evergreen and plan to ride it until it dies
(July 2014) when i will so a complete format and clean install.
(probably of 13.1 which now thought to be the next Evergreen)

Bullshit, I did exactly as said. Works perfect, and this time os123 seems
more stable and intuitive then ever. Even KDE works.

I can't sense any difference, as how would it had been as a proper
installation.

sure it is possible to get lucky and have a smooth upgrade--and,
don't we all know that even a blind hog can find an acorn every once
in a while?

but such a simplicity upgrade path as the one you describe is NOT
going to result in happiness for all who try it.... or even for you
the next time you try it....which is why the supported paths say
things like:

------QUOTE-----
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.

If you upgrade a default system from the previous version to this
version, YaST works out the necessary changes and performs them.
Depending on your customizations, some steps (or the entire upgrade
procedure) may fail and you must resort to copying back your backup data.

As for the live upgrade, it is to be considered a "best effort": it
should work, but it can also fail. It is strongly recommended to make
a full backup previous to the undertaking. If the upgrade fails, you
can then restore and try again, changing whatever is needed to avoid
the previous problem, install fresh, or attempt a live upgrade. . .

It is possible that a jump across 3 or 4 versions can work, but there
is no assurance. If you want to try, make a full backup, get a
comfortable chair, and go ahead :-)

so, it seems your "third-party packages" and configuration
combination was ok for a successful 'upgrade', or you were just
lucky--that does NOT mean it will be for Prof. Filipe's, or any other
random system.

Now you seems to be so fucking stupid. Linux is Linux, idiot. You just
upgrade the soft to a higher version, without formatting and all the shit.

[DenverD]

good luck, you will need it.

concerning the above statement. If you save the downloaded rpm's
IE the updates. You could then use it for how ever long you want.
or until it no longer supports your used hardware.

I could go back to 12.0 and install every application i used if i
wanted to.

[DenverD]

sure you can run it forever, but the problem is that security patches
will stop being prepared for it after July 2014...so all security
vulnerabilities found (in say the kernel, for example) will NOT be
patched in your still running but 'not supported' 11.4

and, since the "bad guys" can see and study the newly known
vulnerabilities in the kernel, they can rather easily target and
krack, your out-of-date system..

no matter if you have every rpm ever distributed for it--you will
have NONE to fix the security problems discovered after July 2014,
and your 11.4 becomes a very easy target to exploit!

see?
