A quick update here:
I'm marking the topic as [SOLVED], after searching for solutions for 5 hours I'm finally importing mails to Zarafa.
Things to do:
Deactivate Webmail in "Module Status" menu
Check IMAP and IMAPS gateways under "Groupware" menu (*methink* IMAPS alone would do it as well, will check it later)
I suppose you have the same user in the new system as in the old one
Run this command, pay attention to the colored parts:
imapsync \
--host1 ip-address_existing_ebox1.4-server \
--user1 user@domain.xx \
--authmech1 LOGIN \
--password1 password_user \
--host2 ip-address_Zentyal2.x-server \
--user2 user \
--authmech2 LOGIN \
--password2 password_user \
--noauthmd5 \
--sep2 “/” \
--prefix2 “” \
--syncinternaldates \
--skipsize \
--useheader subject \
--useheader date
explanation: dovecot on Ebox1.4 expects the username as
user@domain.xx whereas Zarafa wants only the user part of the email address (me not paying attention cost me 5 hours....*grml*)
Right now I'm trying to figure out, why the Zarafa Server Migration Wizard won't connect to the new box. I opened "any TCP" ports on the new system temporarily (it's on the intranet, no worry), but still I get "Cannot find Zarafa serever on this location or port"
To get the Migration wizard running at first you have to install the Zarafa client (matching the Zarafa server version!).
@modarators: could you plz mark the first post in this thread as solved? I'm not the thread-starter, so I can't do that. thx
