I have a really large forum, over 2M posts. I tried importing it but it was really slow that it took almost 50 hours to import on my test server (shared hosting) I migrated my users to a new VPS with a fresh install of XF with the promises of bringing the old forum over to the new server as soon as possible. If I could import it into XF I'd do it, but I want the old information to be an archive not live area, and the same for the user names. What I was able to do in old VB imports was replace the email with no email address so there was no match, that gave the imported user an unusable state, but allowed the import to complete without issue. Is there a way for me to do something similar?
