I was coming to a similar conclusion. Since this is a production email server, it must be up sooner than later.
The easiest will be to start from scratch and rebuild. To that end, I will dive into 7.2 Alpha 3 and mirror the setup.
Later I may need help moving SOGo data if it is not in vmail folder suite.
Thanks for your invaluable help to this point. I’ll be back at you later (no home life tonight…)
LATE NIGHT UPDATE
It is now operational on NS 7.2 Alpha3.
The note that I read in the announcement details for Alpah3 warned that there is currently no upgrade path from Alpha2 is all too true. The fact that performing a software update upgraded me to Alpha3 was not expected.
The issue boiled down to authentication. The server that I am running is a stand-alone server and had neither LDAP or AD authentication active. NS 7.2 Alpha3 forces you into one or the other. The result was that my email user list then became inoperative. Also in the /var/lib/nethserver/vmwail - directory naming conventions changed (on the new system I elected to use LDAP authentication). Roundcube mail now uses directory names that are your fully qualified email. Previously it was just user name (without the @domain.com suffix). That required changing when I rsync’d the dovecot directories over. As well when I sign into roundcube - it has to be the full email address. The funny thing is that SOGo still only uses the simple user name (no domain please). So basic email is working.
Now HOW DO I FIND AND MOVE SOGo Calendars, Contacts and Tasks at the command line level?
