su - zimbra
zmlicense -i /path/to/license/file

Get the information required for the manual activation from the console at "Global Settings->License->Manually Activate License" (fingerprint, activation ID, license ID and version)

Go to support.zimbra.com and log in, go to the license page (use Internet Explorer). Enter the information and download the .xml file.

upload the .xml file and enter:

zmlicense -A /path/to/activation/file

Check for successful activation with
