I have a zimbra mail server(open source) installed on a IBM server. "7.2.2_GA_2852.RHEL5_64_20121204211814 RHEL5_64 FOSS edition" on "Red Hat Enterprise Linux Server release 5.4 (Tikanga)" "x86_64". The mail server is having approx: 250 users. I wish to make a standby server, for that purpose i have installed same copies of red hat 5.4 and zimbra 7.2.2 on desktop pc. Zimbra is working successfully on desktop pc. Can anyone tell what i have to do next to transfer (copy) all users with their configurations from current server to desktop PC.
