The regular license can only be installed on the Zimbra 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 mailbox server.
When you purchase, renew, or change the Zimbra license, you must update the Zimbra mailbox server with the new license information. Use the
Update License Wizard from the administration console’s Global Settings to upload and install a new license and to update an existing license, or you can install or update the license using the
zmlicense CLI command. See Appendix A, CLI Commands,
“zmlicense” on page 270 to use the CLI command.
