The replication protocol in 2.4 is not compatible wit 2.3.

There is no easy way.  I'm rsync'ing one account at a time between 2.3 and 2.4 with IMAP/POP and LMTP access disabled, followed by a reconstruct, and then enabling IMAP/POP and LMTP access.

Many terrabytes to go.

You could also look at imapsync but its slow.
