Another site wants me to import all their information into my forum so that they will no longer have to admin their site. The site is in ip.board, but I think I can convert that to phpbb. Will the Threads phpbb importer append the content or do you have to use it on a clean install?

Thanks.

Threads PHPBB importer will import PHPBB2; it will add the content and users without issue; if you've imported from a prior forum for your own site, it'll append a siteid for the new site for the import map if you edit the importer (if you WANT to anywho)

Great. Thanks for the info.
