XF 1.4 Live while Importing

Importing the posts can take hours and hours...

Is there any issue with having the forum open for members to post while the import is still ongoing?

You can't have people posting, etc. on the source forum while it is being imported to XenForo, nor can you have people posting on XenForo.

Both forums must be closed during the import.
I am doing a test import currently. I am up to the point of importing all the posts. I was able to post to the new XenForo seemingly without issue.

What problems will happen if I leave the destination XenForo open and someone posts while import is ongoing?

I understand that the source forum must be closed.

Well even without that other inconsistencies could be created. The official advice would be to keep everything read only while importing.
