I want to import part of a ZB forum using this: https://github.com/djm/zetaboards-backup but my board on xenforo exists. Is it possible to import everything this backup allows to be saved without erasing my current subforums, forums, and topics?
Can you explain what a double import is? Import from ZB to mybb for example and then mybb to Xenforo? I only want a small portion (maybe 15%?) of the forum I'm importing. I want the users and a percentage of the topics. That's all. This is possible?
Yep, that's the concept of what he was referring to. It requires an import into something we can import from. Note that this can reduce the quality of the import (as it's now dependent on an extra step). It's also more time consuming.
For an individual step, you need to run the full step (and any steps it requires before that). That means you would need to import all of the threads and then remove what you don't want after completing the import.
