We (GATEOverflow) have developed a plugin that lets you restructure posts on a question page without losing any data — same postid is kept, so votes, flags, and edit history are fully preserved.
What it does ?
Every comment and answer gets a Convert button (renders as a standard Q2A button, works in Polaris and Snow Flat):
- Comment → Answer, Move to another parent, or New Question
- Answer → Comment (child comments & follow-on questions handled automatically), or New Question
- A Manage Posts page is also available for bulk operations.
Other details
- Points and search index recalculated correctly on every conversion
- Dark mode support
- Permission-controlled (Editor / Moderator / Admin / Super Admin)
