Migrating sqlite to mysql

I have been using ownloud for quite a time now and i just upgraded to 10.4 and its complaining that I should not use sqlite for multiuser deployements which it never complained about before. So i have a mysql running on the same server and I want to migrate to it but it seems the migration will flush everything:
mrjake@pandora:/var/www/owncloud$ sudo -u www-data php occ db:convert-type --all-apps mysql root 127.0.0.1 owncloud
Enter a new password:
Creating schema in new database
The following tables will not be converted:
oc_account_terms
oc_accounts
oc_addressbookchanges
oc_addressbooks
oc_calendarchanges
oc_calendarobjects
oc_calendars
oc_calendarsubscriptions
oc_cards
oc_cards_properties
oc_dav_properties
oc_dav_shares
oc_external_applicable
oc_external_config
oc_external_mounts
oc_external_options
oc_federated_reshares
oc_files_trash
oc_migrations
oc_notifications
oc_properties
oc_registration
oc_schedulingobjects
oc_share
oc_share_external
Continue with the conversion (y/n)? [n]

So whats the point of migrating if i need to restart from scratch or is there a work around.

Thanks
