The other day I was trying to remove prefixes from the tables in a DB.
I exported with PHP-MyAdmin, edited with MetaPad & imported with PHPMyAdmin.
This procedure I have done several times, and the results arent identical:
sometimes I cant import, because some duplicate errors, otherwise I manage to import succesfully but I cant create new nodes (duplicate errors when submitting).
My conclusion is that something I do is wrong, because Ive exported and imported thousands of times without any issues. The only times is when I try to remove prefixes.
