The regular license can only be installed on the ZCS system for which it is purchased. Only one Zimbra license is required for your Zimbra Collaboration Suite environment. This license is installed on the Zimbra mail server.
When you renew or change the Zimbra license, you must update the Zimbra server with the new license information. Use the
Update License Wizard from the administration console’s Global Settings to upload and install an updated license, or you can update the license using the
zmlicense CLI command. See the Administration Guide, Appendix A, CLI Commands.
Current license information, including the number of accounts purchased, the number of accounts used, and the expiration date, can be viewed from the Global Settings on the administration console.
