The importer preserves original dates and maps forums to spaces. Always run with --dry-run first to preview counts, take a database backup, then run the real import. It batches large datasets so timeouts are not a concern.

One caveat for larger communities: keep an eye on the indexes. At a few thousand rows the difference is night and day.

Strong agree. Good defaults beat a wall of toggles every single time.

Appreciate the clear steps. The dry-run tip in particular saved me from a mistake I would not have caught otherwise.

Solid breakdown. The only thing I would add is to back up before making the change — better safe than sorry.
