Debian Buster (10) is soon EOL so Wikispore servers will need to be replaced with ones based on Bullseye (11) or (preferably) Bookworm (12). See: https://wikitech.wikimedia.org/wiki/News/Buster_deprecation
Requires T319167: [EPIC] Upgrade MediaWiki-Vagrant to Debian Bullseye or T365935: [EPIC] Upgrade MediaWiki-Vagrant to Debian Bookworm.
Previous migration: T321968: Rebuild Wikispore Vagrant box on Buster

This will be harder than I thought as there is no Vagrant base box for Bullseye + amd64 + LXC. We'll either have to build our own per https://github.com/fgrehm/vagrant-lxc/blob/master/BOXES.md (T322450: Build MediaWiki-Vagrant LXC Buster base image, except for Bullseye - there are some extremely old tutorials here and here) or finally migrate off Vagrant (T322991: Consider another orchestration system for Wikispore).
A possible approach to meet the Jul 15 deadline is to build new Bullseye Cloud VPS boxes, and copy the existing Vagrant boxes over as they are. (Vagrant doesn't really care about the host OS, it's just that Buster-based Vagrant boxes cannot successfully provision anymore, so they are basically frozen in their current state.) I have never tried to port Vagrant boxes between Linux machines, but in theory they have export/import functionality for that so I think in theory it would be straightforward.
I'll try this over the weekend.
