Different mailbox size after migration

[armitage318]

Hi,

I need to migrate account from

Release 5.0.10_GA_2609.DEBIAN4.0 DEBIAN4.0 FOSS edition

to

Release 7.1.0_GA_3140.RHEL5_64_20110329150833 CentOS5_64 FOSS edition

I tried the script:

/opt/zimbra/bin/zmmailbox -z -m $USERNAME getRestURL "//?fmt=tgz" > /tmp/$USERNAME.tgz

/opt/zimbra/bin/zmmailbox -z -m UserEmailAddress postRestURL "//?fmt=tgz&resolve=reset" /tmp/username@domain.tld.tgz

I notice that the size on destination server is much smaller than the initial one.
For example:

$ zmmailbox -z -m mailuser@domain gms
522.03 MB

The .tgz is around 120 MB.

I copied the .tgz to destination server and imported it. After migration this is the result

$ zmmailbox -z -m mailuser@domain gms
182.19 MB

It is a bug? Should I use imapsync? Imapsync is fine but the transfer is ofter interrupted with "out of memory" error..
Thank you very much

Fixed in 7.1.3 - Bug 56458 - Mailbox export returns a corrupted tarball
