I have an old website that has a lot of entries. For the sake of seo I would like to move everything in archium form to nodebb. Can I do it? Does it make sense? How do I do it? Just the news is enough, although I have a lot of comments written for over 10 years! Thanks for all the tips !

Did you even read what I said? I wasn't saying that WordPress is worse than NodeBB or anything like that. I said that it's nonsensical to expect to be able to move from forum software with categories, topics, posts, replies, chats, etc to a blog system which doesn't even have built-in comments AFAIK.
