No, you can not. That is just what this whole bug (MySQL don't call it a bug, but a limitation to the functionality

) is about.

To migrate to a previous version, you will need to use the compatible parameter. Once you use the compatible parameter, there will be no information about AUTO INCREMENT columns in your dump anymore, making the database unusable for vBulletin after a restore (see MySQL bug: http://bugs.mysql.com/bug.php?id=14515)

You can also find threads about this at vbulletin.com.
