Post Import Causes Data Reset.

Hello all, I’ve 2 sites, of which im porting content from 1 over into #2, Im using the simple WordPress Export and Import plugin, my process is straight forward and using the typic xml option for posts.

What happens is that when i import to site #2 immediatly after the import which says is successful the site requests a database update which i do. when its done, it resets the database to its original state. Zero posts etc.

Ive synched versions of both sites, course i tried it before upgrading. always the same thing, database update which is successful then its reset.

Regards
