You want to transfer this data to server but use InnoDB engine instead. You execute the following commands: ServerB commands:
Shell＞ mysqldump –u root –h server –no-data apps userdata | mysql –u root –p apps
Shell＞ mysql –u root –p –h server –e 'ALTER TABLE 'apps','userdata' ENGINE=InnoDB;'
Shell＞ mysqldump –u root –p –h server –no-create-info –order-by-primary apps userdata | mysql –u root –p apps
