I don't see my email of accounts after migrating

Hi friends
I backup from Zimbra 7.2.0 on centos 5 and the size of backup was 30 G.
I transfer backup files via rsync command to new server.
In new server i install centos 6 and zimbra 7.2.2 with different domain from old server.
In restore backup when i select the backup path and next i see domains and select all and at the next time i don't see any account to restore.
I replace the backup directory with zextras directory in /opt/zimbra/backup/zextras and run full scan and find accounts.
but when i restore 200 accounts i don't see any email in mailbox of accounts.
