I've read this guide: https://xenforo.com/community/threads/importing-guidelines.25325/ and I'm wondering about the retaining content ID's.
Currently, my live forum is running Vanilla and behind the scenes I'm building up my Xenforo forum. Adding all the trophies I have on Vanilla, making sure everything looks awesome, adding some pages and some add-ons. The works!
I've used the import function to take a "snapshot" of the live forum and work of that. In the meantime the live forum is still being used. Is it safe to import a final version once I'm ready to switch over? There will be problems with the content ID's I imagine?
