The bind setup is based on config files and not on a mysql database, this makes switching to bind a bit more complicated. If you want to switch form mydns to bind, you have to uninstall mydns, then install bind, then run the ispconfig update.php and select to reconfigure services. Then go to the ispconfig server settings and check that the path for the named.conf file and the directory for the bind config files is correct. Afterwards you will have to edit every dns record (zone) in ispconfig, change a value like the ttl and click on save, so that the bind files get written for this record.
