over a year ago, I imported many vb 3.8x forums into one single xenforo forum successfully. This is now forum "A".
At the same time, I imported another one single vb 3.8x forum into one single xf forum. Also successfully. This is the XF forum "B".
In the meantime I upgraded both xf forums to version 1.2.3.
Now I want to import today the XF forum "B" into XF forum "A". So A is the master forum, which will stay. After the import, "B" will no longer exist as a stand alone forum.
Since many imports have been made with these forums, do I have to pay attention to specific issues before starting the import? Also for the redirects etc.?
It could be, that some users are registered in both forums. Sometimes with the same name and/or email address, sometimes with different email address or same email address but different username.
