upgrade from 10.3 -> 11.3

English Install/Boot/Login

hi,

i am upgrading 10.3->11.0 (upgrade is recommended only stepwise). now the question is whether i still do 11.0->11.1->11.2->11.3, which is some (maybe not necessary) work.

for that i’d like to know how the convention of minor upgrades looks like (11.x)? i guess the online update + fixes is always available for all major versions?

i guess when 12.0 is coming out i will anyway have to take the full update path (11.1->11.2->11.3->12.0)?

after finishing 10.3->11.0 do i have to reboot before doing 11.0->11.1? if going the full upgrade path i would like to avoid reboots each time.

thanks for help.

You can upgrade from 10.3 to 11.2 straight if you do it via an installation medium (and that installation medium means DVD only).

What’s the point of this? To avoid a reboot???
Don’t be silly, do a fresh install of 11.2, and keep /home.

i see, though i read that is highly recommended to do it always step by step. i do always install through DVD medium (in my case i placed the iso image on the server box). are you sure when using DVD image style that there is the same problem-occurrence-risk upgrading from 10.3->11.3 as 11.2->11.3?

if bypassing minor versions is OK, maybe it is also enough for me to wait for 12.0 and upgrade 11.0->12.0 straight.

well, less server downtime (apache2 is running). there are also some things in /etc and /srv which i definetely want to keep.

Note, there are some obvious pitfalls here if you are running old PHP applications - first of all, 11.2 ships with MySQL 5.1 and PHP 5.3.0 which will cause old poorly coded php scripts to explode magnificiently.

Make sure your software is up-to-date (especially if you run CMS or similar systems) before upgrading to 11.2 (perhaps do it in a virtual machine first?)

yes, i tested the webapps. they are compatible for latest mysql+php versions.

now i finished successfully upgrade to 11.0. i guess i will do the next upgrade when 12.0 comes out. i guess i still get security fixes through the online update, so waiting for 12.0 shouldn’t be critical to me.

just to ensure: doing a 11.0->12.0 straight through DVD iso-media will work fine from OS point of view (compatibility of script and other apps to upgraded packages is of course another thing to check).

setting up a ‘test env’ virtual machine is a good idea. let’s see whether my provider makes this possible (though it is a root-server i should ask the provider-admins whether this setup impacts the networking)

Your suggestion is going to take days, and I would not let a critical webserver run on during an upgrade.
You will anyway meet the MySQL trouble, whether you upgrade or perform a clean install. Better invest some time reading on that matter and perform a clean install.

If you’re talking about Joomla I can help you out.

I could never do a clean upgrade from any of the previous versions. There were always some unexpected issues and that leads to unexpected downtime.

Any server machine running in Production must have a better plan if the services are really critical. Typically, a parallel (real or virtual) machine should be set up and tested first.
