I installed and configured my VMware Zimbra Mail Server (network editions) last year with 100 mailboxes licenses activation. My license is expiring on 5th of the March 2013. I start the process of procuring but it will take time and may be exceed the expiry period.

My Questions are

1. What will happen to the server ? if my license expire to network edition (e.g. i will be unable to create accounts, backup etc)?
2. My current license is for 100 Mailboxes/users/clients and now we are planning to procure 50 mailboxes/users/Clients license. Is it Possible? and in 100 CALS we only consumed 37.
3. How to deploy? i mean simply open the GUI of mail server (, and upload the new license.xml(what ever) file?
