Merging two VB 4.1.12 forums
 

I'm attempting to merge two VB 4.1.12 patch 3 forums together. I'm doing tests in a DEV area.

I've worked to equalize the two forums. The forum names are identical, the two sites are set up as identical as I can make them.

I've run the test import twice but even though everything says it's working fine and there are basically no errors the finished test forum is missing all the imported threads and even many of the existing forums in the target site are deleted and missing all threads and posts after.

Seems like this would be the easiest of forum mergers. Is there some issue merging to VB 4 forums I should be aware of?

6 years ago I imported a phpbb forum into a vb 3 forum and it worked much better than this.
