MySQL master slave replication from first binlog position

I have a couple of live databases that need migrating over to a new server. These are large databases constantly in use.

I want to setup replication with a slave on the new server and begin porting data across. However, I'd like to try and avoid doing a mysqldump on the current master data to get the initial binlog position as I don't want to lock down the database for an extended period of time.

Is there a way that I can find out the earliest master_log_pos so I can start replication from the very start? If not, are there any other solutions that avoid halting transactions (as much as possible)?

If I understand you correctly, I think Percona's Xtrabackup is helpful for you.

Xtrabackup is hot backup tool which makes you can backup MySQL while it is running.

With Xtrabackup you can make data backup quickly even if data is large and move backups to slaves.
