upgrade 3 (nearly identical) mediawkis from version 1.26.4 to 1.33

I have an old mediawiki installation 1.16.4 from 2016 on a managed webhosting site, it ran under php 5.6. Each has some 100 articles in it, no edits since that time. I deployed it, disabled editing and forgot about it. Recently, my webhoster automaticaly asked me to upgrade my php to 7.3. I did this and now see that these wikis do not run any more under the new php version. Unfortunatly, my provider doesn't allow me to change back to any older version x.x php version any more. So I need someone who can convert these thee mediawikis to the latest version 1.33. what can be provided are mysql dumps from the three databases of the last days and months as well as ftp access to the webspace.
