I followed instructions at:

http://wiki.koha-community.org/wiki/Backing_up_Koha
http://wiki.koha-community.org/wiki/Koha_on_Ubuntu

For backing up 3.02 database I ran "mysqldump -u kohaadmin -p
--ignore-table koha.sessions --ignore-table koha.zebraqueue koha >
mydatadump.sql" command.

I then installed a Koha 3.06.3 on a fresh machine. Before importing
mydatadump.sql I dropped and re-created koha database on the fresh
machine.

This error is now gone :-). This time I didn't drop and re-create koha
database on the fresh machine. I imported 3.02's mydatadump.sql on top
of existing 3.06.3's new database.
I suspect " --ignore-table koha.sessions" bit might be the reason for
the above error. I also used a different browser after importing the
database. Maybe this part helped to fix the error.

Thanks for help Chris!
