    Default Is zmztozmig reliable?

    Hi.

    I am performing a migration from a debian32 to an ubuntu64 6.0.8 oss.

    I decided to give a try to zmztozmig, since I saw in blog posts and elsewhere as official zimbra tool to move a mailbox.

    I ran it on a big one, and after it said everything was successful I gave a quick comparison between the two installations: on the old install the account was 4.2G, on the new one 3.3! That's a considerable difference!

    I have to say that on the move, the filesystem passed from ext3 to ext4, but is Zimbra considering size on disk or message sizes? In the second option, as I would expect, the size count shouldn't change. An user shouldn't matter what's the account size ON DISK.

    As I sad, at first sight the account seems to be fully migrated on the new server, but I cannot be totally sure, I have tons of mails and subfolders in that 4G of mail.

    How can I be sure it moved everything?
    Can I trust zmztozmig?

    thanks

    I used it several times without issue.

    Check the quota on destination server are not set too low, because zmztozmig doesn't show a "clear" error message when it can not import everything because of quota.

    thanks for your reply.

    I have set message and max upload quota to 70Mb, which is above the limit on the old server, so it shouldn't be the issue.

    I was thinking of the mailbox quota.

    great, I just copied 10 accounts using this tool, and everything SEEMS ok.
    But even not, because on an account I sadly lost ONE MONTH of email in inbox!!!!

    I checked in the TGZ the email exists! It seems they are not imported on the destination account!
    but I cannot understand why. I removed duplicate check, the file size limit is 120Mb, what else could be!
    The strange thing is that it's also missing a contact created in this time frame.

    I re-ran the import on that account, several times, and NOW I got the missing email.
    Was pretty scary.

    ...
    No, definitely it didn't copy ALL messages.
    Cannot figure out the reason.
