I am finally taking the plunge and converting my VBulletin 3.8 site to Xenforo. I have ~11 million posts to convert over. My problem is I've allowed HTML posts for years. I'm fine moving forward with the s9e media plugin for YouTube, Twitter, etc. media embeds, but I have years worth of past posts that use IMG tags and full embed codes for tweets. In my test conversion, those posts are obviously just raw HTML code. Are there any pre-written queries I could run to convert images, tweets, youtube HTML posts to friendly media embeds for Xenforo? Thank you!
