At least in manual mode (not rolling)?. 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. > > Cheers. > > > --- > > > EGOITZ AURREKOETXEA > Departamento de sistemas > 944 209 470 > Parque Tecnológico.
