We have 4.5 Million posts, but for the most part it is a slow moving chat room. I'm not sure many threads are revisited after a couple weeks have past. If/when I migrate the forum to a contemporary software package - should I just leave the 4.5M posts behind and just transfer the structure and user accounts over?
That would mean every forum would start fresh, but there would be a link to the old archives.
Any opinions?
