Upgrade

Handboek.petities.nl gebruikt Mediawiki versie 1.24 sinds 27 november 2014.

Since Version 1.36, MediaWiki only commits to supporting upgrades from two LTS releases ago (see phab:T259771). Upgrades from older versions of MediaWiki will have to be performed in multiple steps. This means that if you want to upgrade to 1.36 from 1.23 or earlier, you'll first have to upgrade your 1.23 wiki to 1.27 (or 1.35), and, from 1.27 (or 1.35), you'll be able to upgrade to 1.36.

Upgrading from 1.4 or earlier is potentially complicated because support for character sets other than UTF-8 was dropped

Do not upgrade from a MediaWiki version older than 1.33 to MediaWiki 1.39.1, or you may lose data! Upgrade to 1.35 first.

• Mediawiki 1.25 PHP 5.3.3 or newer is now required to run MediaWiki (up from PHP 5.3.2)

• MediaWiki 1.27 now requires at least PHP 5.5.9. This corresponds with HHVM 3.1.

• MediaWiki 1.31 requires PHP 7.0.0 or later. Although HHVM 3.18.5 or later is supported, it is generally advised to use PHP 7.0.0 or later for long term support.

• MediaWiki 1.35 no longer supports PHP 7.2. PHP 7.3.19 or later is required.

• Mediawiki 1.39 MediaWiki 1.39 drops PHP 7.3 support, and requires PHP 7.4.3 or above.

Responsive interface of Mediawiki

it is not optimized for mobile devices. Unless you add additional skins or extensions

Skin:Minerva Neue is bundled with MediaWiki since version 1.38. Its mobile mode requires installing Extension:MobileFrontend. This is the method Wikipedia uses.

Cerberus

De helpdesk gebruikt Cerberus Version 5.5.2. (Build 2011083001)

server requirements version 10.3.7 PHP 7.2 (64-bit) or later, MySQL 5.6 or later/MariaDB 10.2 or later

The upgrade, from any version post 4.0, is a direct upgrade. Yes, Cerb will run all the intermediate patches, but you can point the newest code at your database (back it up first!) and it'll upgrade from there just fine.
