How to upgrade Web & Traffic Quota for all existing clients (globaly)? For example: I have changed limits in client Limit Template, but previously created clients remain with old limits. "Resync" tool does not hel here.. Thanks for the advice!
To my knowledge it is not possible yet. You need to manually change every quota. The client can also change as long as you did not create as admin.
These settings exist just in MySQL and when a website or mailbox is changed then the sum of website quotas of the client is compared against thie value in the client table, so you can update them with a mysql query in phpmyadmin.
