I'm trying to move my old bugs from a bugzilla database 2.18 version
to a new install in a new machine with 3.0.4 or later version. I run
the following command:

mysqldump --opt --password=sockmonkey --user=bugs bugs
>bugzilla_backup.sql


mysql --password=sockmonkey --user=bugs bugs < C:\bugzilla
\bugzilla_backup.sql

I have obtained some errors:

Software error:

'profiles.disable_mail' in 'field list' [for Statement "

id,profiles.login_name,profiles.realname,profiles. mybugslink AS

Can I import/export database into different bugzilla version?

Thanks a lot.
