Actually https://wiki.wikimedia.it/ is running MediaWiki 1.26.4 but some time is passed since 2015 and now this version is no longer supported.
We should upgrade the installation to assure maximum support to latest security patches (some of them were not back-ported) and maximum support for post-2015 features like VisualEditor, the Extension:Thanks and other awesome things that could be appreciated by Wikimedia Italia members.
In short we should take some time to:
- assure a backup
- check if upgrade is feasible on the same server
- upgrade from 1.26.4 to latest LTS 1.37
- eventually adopt the cute Debian mediawiki package maintained by User:Legoktm
- bonus point: track A/B configuration changes of our LocalSettings.php in Wikimedia Gerrit or whatever code hosting the community is discussing now between Phabricator and/or GitLab and/or GitHub and/or a nextCloud directory called wikina-final-version-really-really-final-ok-really-ok-ok-2020.zip asd
Also after the upgrade we could wait some time (few days?) before installing our new extensions, in order to test the fresh upgrade as-is and be sure that everything works without regressions.
