I am not an mysql expert.
The E-Zest way i know of is via phpMyAdmin (a web based Mysql Frontend)
this is the only way I work with mysql.
If you still have your old database on your old system up and running
you can just backup the tables that you wont, then restore them to your
mysqldump --add-drop-table -u mythtv -pmythtv mythconverge [Table Name]
The "--add-drop-table" command will drop the table before restoring it.
just looking on the web i found:
Hope this helps
let me know how things turn out
