I made the mistake of not backing up the database right after installing xenforo. I imported users, usergroups, and forums from my live vbulletin forum. Not the posts & threads. I am saving those for later as I have xenforo on a test setup where I am finalizing the design and making sure everything can get carried over. Is it possible to import all the data and then run it again in a few days and grab only the newest data that was missed the first time (users, threads, posts) or does the import need to go through the complete process and grab everything again? I'd like to have as much data from the live site as possible on xenforo to make sure everything is good to go. But I've already imported data that will be stale in a week or two once I'm ready to go live. How can I grab this new data?
