I've installed on ubuntu next version of ZCS:
Release 6.0.2_GA_1912.UBUNTU8_64 UBUNTU8_64 FOSS edition.
Also I configured latest version of ZCS on FreeBSD:
Release 7.1.1_GA_3205.FreeBSD_amd64 FreeBSD_amd64 FOSS edition.
Question: How I can move all data from Ubuntu tu FreeBSD (include mail accounts, domains, and all data on the server, I mean alll users mail)?
