After moving ZCS from debian to ubuntu and upgrade from 6.0.1 to 6.0.12 i can't display quota usage by users in administration console and with `zmprov gqu server` - it only displayed for users created after migration. Quota usage by old users is available in user's web ui, imap and using zmmailbox.
How can i fix this? I can't find any difference in configuation of old and new users. May be there some mysql or ldap wasn't recreated or some files are missing.
