Migrate Mailboxes Dovecot/Mysql/Maildir to Zimbra

[thiago.sapore]

Hello everyone,


I'm new here and don't have much knowledge of the interface of Zimbra yet, but I've read a lot of content.
I'm researching how to migrate the mailboxes from a server where the MDA is Dovecot, the database is Mysql and the format is Maildir boxes.
Today I've migrated the information from the mysql for Zimbra, User information, password, quota's OK.
Now I'm see a way to use the imapsync tool, but without the need to pass password1 and password2 of all accounts, because are more than 2000 accounts, the password are in format Crypt at Database.
Someone in the Forum has a scenario like mine and what was the procedure for copies of the boxes?
I'm thinking about 3 ways to do, I don't know if it rolls..., reset the password for all accounts to perform the migration and verify if on the Console Zimbra has something like access First change your password!
Or copy the boxes via rsync to another server, but I don't know if this will work, I don't know how it manage the home, the maildir, index, suid, dates etc ...
Another option would be to decrypt the password for all accounts via a script ready available on google, someone knows something like this or that have done this way?

Well that's it, now I go forward my thanks for reading and help.

Regards,
Thiago

I would recommend using imapsync to do the mail migration, take a look at these wiki articles for some more information:
Guide to imapsync - Zimbra :: Wiki
Imapsync from courier-imap without passwords - Zimbra :: Wiki

Hi,

What i've done is (as Zimbra zmprov support crypt password format),
I setup a generic password on both side and after transfer, I restored the current one.


Regards.
