So you are setting up a new server for zimbra 7?
I would try copying the server partitions to the new server and then upgrade to 7 (by running the installer install.sh).

ps: this is not a fix but a workaround to your issue.

Hi

Yes i had installed the new zimbra server & using account migration wizard trying to import the accounts & the mails of the users from another zimbra server

Did you find a resolution? Having same issue.

[prasadpimple]

not yet working with zimbra support hope this issue will get resolved in next release

[robncar]

We were able to get the migration wizard to work with a commercial cert on the destination server. The self-signed would not work for us.

Is using a commercial cert the only answer to this problem? I'm having the exact same problem. SSL for IMAP is turned off so I'm not sure why the two servers are doing an SSL handshake.

I know this is an old post but wondering if anyone having this problem has made it work.

[Bill Brock]

Figured the problem out myself.

How did you resolve the issue?

Also, will the migration wizard in the ZCS OSE 7.x admin console migrate resources/shared calendars from ZCS 6.x as well? If not, is there a good migration strategy for these?
