UBB.threads PHP Forum Software Community Forums News and Releases Pre-Sales Questions Running IPB want UBB but need import/conversion tool

The only imports available at the moment are phpbb and VB - Hopefully once 7.3 is stable, other importers will be written including FusionBB.

Any announcement will be made here as soon as a new importer is written.

Your other alternative is to go via phpbb - import into that and then into UBB.Threads.
