what you are trying to do is enable replication
2.3 is supported it is my understanding this was removed in 2.4 (unless you buy a contract)
Paul, replication is not available even with contract. There are some open source alternatives if you want to use replication, e.g. wormhole plugin.
Marc, your problem is that you are trying to setup sync over IMAP. If you are attempting to do this for migration, see https://doc.dovecot.org/2.4.2/core/admin/migration.html
If you are indeed trying to do bidirectional sync with tcps you need to configure, on both servers
service doveadm { inet_listener 12345 { ssl = yes } }
doveadm_password = foobar
and then use
doveadm sync -R1 -u USER tcps:OLD_SERVER:12345
