At least with LLMs, we can just write a query to migrate the export to whatever target format we want. The main issue is just breaking 20 years worth of inbound links.
I mean with LLMs you just copy-paste in the input format of your new CMS and then upload your export file. Even if it only took 15 minutes before, it now takes 0 minutes.

That is annoying indeed - it would be nice if the Web had
some way to keep links eternally valid. But people didn't
even manage Digital Object Identifiers (DOIs) to work beyond
the death of the publishing companies that issued them...
Perhaps links could be auto-replaced to archive.org links if they ceased to exist?
