I'm assuming that you are trying to keep your content, styling, and markup maintainable or even upgrade it as you move the pages though? I'd imagine this is a different scenario. The content created by users will be put through some AI transformation and it will be completely and utterly unmaintainable slop (and a significant portion of it would have already been that anyway before they started since it's user submitted). They aren't going to care that much if some edge cases break. Users can go fix that themselves. It seems much different to me than trying to delicately move something you care about.
