I'm trying to migrate a open source version 3.1.4 (debian) on a new server with the 4.5.9 (debian) open source version installed.
I tried to do a imapsync but the first server dosent let imapsync connect. (I tried with, ssl, login, plain(clear text activated in the admin console) etc.
Is there a way to migrate every account from the old server on the new server without imapsync ? ( a zimbra utility perhaps ?) I looked on the website and forum and found nothing on this... maybe I missed something.
Thanks for any help on this.
