Thanks Alex.

I'm in even worse situation with wiki.laptop.org, and last looked into
this in December 2018, so I don't think I can be of any help.  What
blocked my upgrade was use of the Semantic MediaWiki plugin, but I
don't know if Sugar Labs Wiki is using that.

Here's my list of links in my notes of the day.
